Question

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

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

Answer 1

Answer:

  x = 7

Step-by-step 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
