Question

Find the slope-intercept equation for the line with the indicated slope and y-intercept. Slope-3; y-intercept (0,31)

Answer 1

Slope-intercept equation:

y = mx + c

m = slope

c = y-intercept

y = - 3x + 31

Answer 2

Answer:

$y=-3x+31$

Step-by-step explanation:

the general form of the slope-intercept equation is as follows:

$y=mx+b$

where $m$ is the slope of the line, and $b$ is the y-intercept.

In this case we know that the slope is:

$m=-3$

and the y-intercept is the value of $y$ when $x=0$, from the given point the y-intercept is at (0, 31) so the value of y, when $x=0$ is $31$, thus:

$b=31$

and we substitute this values in the general form of the equation:

$y=mx+b\\y=-3x+31$

the slope intercept equation is $y=-3x+31$
