Question

The pair of points lies on the same line with the given slope. Find x

(3,-13),(x,-25);slope= -3

Answer 1

x = 7

Explanation:

The point-slope equation of the line is ...

y -(-13) = -3(x -3)

Substituting -25 for y, we can solve for x:

-25 +13 = -3x +9

-21 = -3x . . . . add -9

7 = x . . . . . . . divide by -3
