And provide the steps to solve this!

slope = m = (y2 - y1)/(x2 - x1)

(y2 - y1)/(x2 - x1) = m

(-1 - 1)/(-1 - x) = 2/7

-2/(-1 - x) = 2/7

2/(x + 1) = 2/7

1/(x + 1) = 1/7

x + 1 = 7

x = 6

x = 6

The formula of a slope:

We have the points (-1, -1), (x, 1) and the slope m = 2/7. Substitute:

    cross multiply

     use distributive property

     subtract 2 from both sides

       divide both sides by 2
