Question

Write the equation of a line that passes through the point (-2, 1) and has a slope of 4.

A. y = 4x − 7
B. y = 4x + 1
C. y = 4x + 3
D. y = 4x + 9

Answer 1

D. y = 4x + 9

Explanation:

a line that passes through the point (-2, 1) and has a slope of 4

y = 4x + b

b = y - 4x

b = 1 - 4(-2)

b = 1 + 8

b = 9

So equation

y = 4x + 9
