The slope of a line is 2/3 and it passes through the points (-4, 6) and (x, 14). Find the missing coordinate, X

Answer 1

Write the equation for the slope, plug in the numbers, and solve for x.

m = (y₂ - y₁) / (x₂ - x₁)

x₁ = -4

y₁ = 6

x₂ = x

y₂ = 14

m = 2/3

2/3 = (14 - 6) / [x - (-4)]

Now solve for x and finish from here.
