Question

What is the equation of a line that passes through the point (0, -2) and has a slope of -3?

y = -3
y = -3x - 2
y = -2x - 3
y = -2

Answer 1

y=mx+b
b=-2
m=-3

y = -3x - 2

Answer 2

The answer is y = -3x -2
This is because they have told you that the slope is -3, and the slope in the equation is the value attached to x. Since it goes through (0, -2), it intercepts the y axis at point -2, which is why you add the -2 onto the end. I hope this helps!
