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
