If B is nonzero, then the y-intercept, that is the y-coordinate of the point where the graph crosses the y-axis ( where x is zero ), is − C / B, and the slope of the line is − A / B.

This is equivalent to the point-slope form above, where the slope is explicitly given as ( y < sub > 2 </ sub > − y < sub > 1 </ sub >)/( x < sub > 2 </ sub > − x < sub > 1 </ sub >).

A horizontal line has slope 0, a 45 ° rising line has a slope of + 1, and a 45 ° falling line has a slope of − 1.

Two lines are perpendicular if the product of their slopes is − 1 or one has a slope of 0 ( a horizontal line ) and the other has an undefined slope ( a vertical line ).

Also, another way to determine a perpendicular line is to find the slope of one line and then to get its reciprocal and then reversing its positive or negative sign ( e. g. a line perpendicular to a line of slope − 2 is + 1 / 2 ).

* for angular frequencies above it is a line with a slope of − 20 dB per decade since at high frequencies the term dominates and the decibel gain expression above simplifies to which is a straight line with a slope of − 20 dB per decade.

Now the data we are given on the v < sub > i </ sub > for 0 < i < n, namely that they are at least one, is just what we need to conclude that the lower convex envelope is exactly the single line segment from ( 0, 1 ) to ( n, 0 ), the slope being − 1 / n.

Three integral curves for the slope field corresponding to the differential equation dy / dx = x < sup > 2 </ sup > − x − 1.

For a uniform distribution of radio sources at not too large redshift ( i. e. in a ' steady-state, Euclidean universe ') the slope of the cumulative distribution of log ( N ) versus log ( S ) would be − 1. 5.

Data from the early Cambridge 2C survey ( published 1955 ) apparently implied a ( log ( N ), log ( S )) slope of nearly − 3. 0.

Later radio survey data have shown a complex picture — the 3C and 4C claims appear to hold up, while at fainter levels the source counts flatten substantially below a slope of − 1. 5.

The second lunar excursion's primary objective was to visit Stone Mountain to climb up the slope of about 20 degrees to reach a cluster of five craters known as " Cinco Craters ".

The second order reaction rate constant k at 20 ° C for a reaction is related to a nucleophilicity parameter N, an electrophilicity parameter E, and a nucleophile-dependent slope parameter s. The constant s is defined as 1 with 2-methyl-1-pentene as the nucleophile.

In the absence of 1 / f noise in a region where the phase noise displays a – 20 dBc / decade slope, the

Some models have fixed-slope, fixed-frequency high-pass filters at 80 or 100 Hz that can be engaged ; other models have ' sweepable HPF '— a high-pass filter of fixed slope that can be set within a specified frequency range, such as from 20 to 400 Hz on the Midas Heritage 3000, or 20 to 20, 000 Hz on the Yamaha M7CL digital mixing console.

First-order filters have a 20 dB / decade ( or 6 dB / octave ) slope.

The spacecraft landed at 00: 46: 44 UT on September 11, 1967 ( 7: 46 p. m. EST September 10 ) in Mare Tranquillitatis, at 1. 41 ° N latitude and 23. 18 ° E longitude ( selenographic coordinates ), within the rimless edge of a small crater on a slope of about 20 deg.

The Town Clock opened on October 20, 1803 at a location on the east slope of Citadel Hill on Barrack ( now Brunswick ) Street and has kept time for the community ever since.

For example, a slope that has a rise of 5 feet for every 100 feet of run would have a slope ratio of 1 in 20.

The slope of the hill was so steep that the Ottomans could get within 20 metres of the trenches without being seen.

The slope of the downward leg of the gain plot is ( 20 dB / decade ); for every factor of ten increase in frequency, the gain drops by the same factor:

Permeable pavements may not be appropriate when land surrounding or draining into the pavement exceeds a 20 percent slope, where pavement is down slope from buildings or where foundations have piped drainage at their footers.

Its spectral slope ( a measure of body reflectance in function of the wavelength ) is twice as steep as that of other Inuit-group satellites ( 20 % per 100 nm ), typical for red trans-Neptunian objects like Sedna but unknown for irregular satellites.

Venera 9 landed within a 150 km radius of, near Beta Regio, on a steep ( 20 °) slope covered with boulders ( suspected to be the slope of the tectonic rift valley, Aikhulu Chasma ).

The slope with offset frequency in various offset frequency regions can provide clues as to the source of the noise, e. g. low frequency flicker noise decreasing at 30 dB per decade (= 9 dB per octave ).

This high-pass filter has a slope of 18 dB per octave.

Second-order filters have a 40 dB / decade ( or 12 dB / octave ) slope.

Third-order filters have a 60 dB / decade ( or 18 dB / octave ) slope.

Fourth-order filters have an 80 dB / decade ( or 24 dB / octave ) slope.

This means that the slope of the frequency response is limited to 6 dB per octave.

However, it is common to assume that for many sources, the slope of a quantizer SQNR function can be approximated as 6 dB / bit when operating at a sufficiently high bit rate.

A second-order all-pole filter gives an ultimate slope of about 12 dB per octave ( 40dB / decade ), but the slope close to the corner frequency is much less, sometimes necessitating a notch be added to the filter.

A first-order low or high pass filter has a standard response curve which reduces the unwanted frequencies well above or below the corner frequency with a slope of 6 dB per octave.

A fancier second-order filter will reduce those frequencies with a slope of 12 dB per octave and moreover may be designed with a higher Q or finite zeros in order to effect an even steeper response around the cutoff frequency.

Note that the slope is 20n dB / decade where n is the filter order.

Usually expressed in volts per metre, the vector direction of the field is the line of greatest slope of potential, and where the equipotentials lie closest together.

The slope of this line is the specific growth rate of the organism, which is a measure of the number of divisions per cell per unit time.

* at every value of s where ( a zero ), increase the slope of the line by per decade.

* at every value of s where ( a pole ), decrease the slope of the line by per decade.

* at every ( for stable zeros – < math > Re ( z ) < 0 </ math >), increase the slope by degrees per decade, beginning one decade before ( E. g.

* at every ( for stable poles – < math > Re ( p ) < 0 </ math >), decrease the slope by degrees per decade, beginning one decade before ( E. g.

As a result, it is sensitive to the slope of a wavefront, not the wavefront shape per se.

In regression analysis, ⟨ B ⟩ symbolizes non-standardized partial slope coefficients, whereas ⟨ β ⟩ represents standardized ( standard deviation-score form ) coefficients ; in both cases, the coefficients reflect the change in the criterion Y per one-unit change in the value of the associated predictor X.
