Question

Write an equation in point slope form of the line that passes through the point (-2,10) and has slope -4

Answer 1

y = -4x + 2

Explanation:

General equation

y = mx + b

where m is the slope and b is the y intercept.

Givens

m = - 4

Point: (-2,10)

Solution

y = -4x + b

10 = -4(-2) + b

10 = 8 + b

10 - 8 = b

b = 2

Answer:

y = -4x + 2
