Question

What is the equation of the line with a y-intercept of -10 and a slope of 3?

A) y=-10x-3
B) y=-10x+3
C) y=3x-10
D) y=3x+10

Answer 1

C) y=3x-10

Explanation:

Answer 2

C) y=3x-10

Explanation:

All options given are in slope-intercept form.

`y=mx+b`

m - slope

b - y-intercept

We are looking for the equation with a y-intercept of -10 and a slope of 3.

Options A and B have a y-intercept of -3 and 3. So, they are not the best answers.

Option D has a y-intercept of 10, not -10.

Option C has a slope of 3 and a y-intercept of -10.

This means that Option C will be the best answer.

Hope this helps.
