Question

Identify the equation of the line having a slope of -3 and a y- intercept of 7

A y + -3x +12
b y = 3x - 7
c y = 3 + 7
d y = -3x + 7

Answer 1

D.

Explanation:

We can use the slope-intercept form:

`y=mx+b`

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

We know that the slope is -3.

And the y-intercept is 7.

Hence, we will substitute -3 for m and 7 for b. This yields:

`y=-3x+7`

Therefore, our answer is D.
