y=-5x-7

For this question we will use the slope intercept form equation, because we are provided with the slope and the y-intercept.
The slope intercept form equation is
. In this formula m denotes the slope and c denotes the y-intercept.
Since we have both m and b, we can stick them into the formula. Upon doing this we obtain

Simplify

Great job! We found the equation
