Answer:

y = 9x-8

Explanation:

Find y values for x= -3 and x = 3. These will come out to -35 and 19 respectively.

Plug these numbers into the rise/run equation for slope m (y2-y1)/ (x2-x1). Plugging values in and simplifying you will get 54/6, which reduces to 9. This is your m value.

Apply your m value to x = 3 going backwards (x = 2 gives a y value of 10, 1 gives 1, and 0 gives -8). This will give you a y intercept of -8. This is your b value.

Plug the slope and y intercept into the mx + b equation. This will give you y = 9x-8.

There you go!
