Answer:


y = - 4x + 3


\boxed{\frak{Step \: by \: step \: explanation \: : }}

Based on the position of two lines:


m = - 4

Write the equation of linear function

Substitute:


- 5 = - 4 * 2 + b

Calculate the product or quotient:


- 5 = - 8 + b

Rearrange unknown terms to the left side of the equation:


- b = - 8 + 5

Calculate the sum or difference:


- b = - 3

Divide both sides of the equation by the coefficient of variable:


b = 3

Substitute:


y = - 4x + 3
