Question

Which equation represents the graph of the linear function?

A.
y = 4x + 4

B.
y = 4x − 4

C.
y = −4x + 4

D.
y = −4x − 4

Answer 1

By looking at the graph you can rule out choices C and D because the graph given to you is an increasing linear function and C and D represent functions with a decreasing or negative slope.

By looking at the picture the slop of the graph seems to be 4/1 (rise/run) so your slope is 4. And your y-intercept looks like its -4 so your answer is B
