Find the value of r so the line that passes through each pair of points has the given slope. Point 1: (−2,r) Point 2: (6,7) m=12

Answer 1

m = (y₂ - y₁) / (x₂ - x₁)

Point 1: (-2, r)

Point 2: (6, 7)

m = 12

(7 - r) / [6 - (-2)] = 12

(7 - r) / (6 + 2) = 12

(7 - r) / 8 = 12

7 - r = 96

-r = 89

r = - 89
