Question

Find the missing value so that the two points have a slope of (2,6) and (x,

Answer 1

Slope -11/7

Points  ( 2, 6) and (x, -5)  compare to (x₁, y₁) and  (x₂, y₂)


Slope =   (y₂- y₁) / (x₂- x₁)

-11/7 = (-5 - 6) / (x - 2)

-11/7 = -11/(x -2)

1/7 = 1/(x-2)

7 = x - 2

x - 2 = 7

x = 7 + 2

x = 9
