Question

Which choice is a correct equation for the graph shown below?

A y = 2x + 20
B. y = 3x + 1
C. y = 10x + 5
D. y = 15x + 35

Answer 1

C

Explanation:

it starts on 5 and goes up by 10

Answer 2

C

Explanation:

y = mx +b The b is where the graph crosses the y axis. If you look a the graph it is crossing at 5. The m is the slope. It is the change in y over the change in x. If you start at 5 and go up10 and over 1, you will be on the line. So our slope is 10/1 which is just 10
