Question

Write the equation of the line using function notation.

A. f(x) = -2x - 4


B. f(x) = -4x - 2


C. f(x) = 4x - 2


D. f(x) = -2x + 4

Answer 1

Explanation:

(0, -4), (2, -8)

(-8 + 4)/(2 - 0) = -4/2 = -2

y + 4 = -2(x - 0)

y + 4 = -2x + 0

y = -2x - 4

f(x) = -2x - 4

Option A is the answer
