Answer:  1) y = 4x + 5

               2) y = 3x + 2

               3) y = (-5/6)x + 1/3

Step-by-step explanation:

Use the Point-Slope equation:    y - y₁ = m(x - x₁)    where

  • (x₁, y₁) is a point on the line
  • m is the slope

(x₁, y₁) = (-1, 1)     m = 4

y - 1 = 4(x + 1)

y - 1 = 4x + 4

y      = 4x + 5

(x₁, y₁) = (1, 5)     m = 3

y - 5 = 3(x - 1)

y - 5 = 3x - 3

y      = 3x + 2

(x₁, y₁) = (-2, 2)     m = -5/6

y - 2  = -5/6(x + 2)

y - 2 = (-5/6)x - 5/3

y      = (-5/6)x + 1/3
