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

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

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
