Question

Choose the equation is the slope-intercept form, that has a slope of 8 and a y-intercept of -3.
A) y= -3x+8
B) y= -3x-8
C) y=8x+ 3
D) y= 8x+ -3
PLEASE HELP!!!​

Answer 1

Answer:

$\boxed {\tt D. \ y=8x+-3}$

Step-by-step explanation:

The slope-intercept form of a line is:

$y=mx+b$

where m is the slope and b is the y-intercept.

The slope is 8 and the y-intercept is -3. Therefore,

$m=8 \\b= -3$

Substitute the values into the form.

$y=mx+b$

$y=8x+(-3)$

$y=8x-3$    or    $y=8x+-3$

Let's look at the choices. The choice that matches our answer is D. y=8x+-3
