Question

What is the equation in point slope form for the line passing through (10,-9) with slope m=-2?

Answer 1

The equation is y = -2x + 11

Explanation:

Use the general form for a linear equation, y = mx + c
You have been given m = -2 and you have the point (10, -9) so you know that when y = -9 then x = 10
Substitute these into y = mx + c
to get
-9 = (-2 * 10) + c
-9 = -20 + c
and solve it to find c
