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

The answer is C. y = 4x + 4. You can find the slope by rise over run where the rise is 4 and the run is 1. 4/1 is 4. You also know to add 4 as 4 is the value of y when x=0.
