Question

What is the equation of the line in the graph?

A. y = 2x – 2
B. y = x + 4
C. y = 2x + 4
D. y = x – 4

Answer 1

D. Y=X-4 is the correct answer.

Answer 2

Well, we can see that the y-intercept is (0, -4) which means that the line must be:

y=mx-4

And since only one answer has -4 as the y-intercept, y=x-4 is the answer :P
