Question

What is the point-slope equation of a line with slope -3 that contains the point (-8, -4) ?

Answer 1

Since you are given the slope, all we have to do is substitute in the x and y coordinates to
y = -3x + c
-4 = (-8 × -3) + c
-4 = 24 + c
- 24
c = -28
So your final equation is y = -3x - 28
