Answer 1

1. B

Answer 2

2.D

Answer 3

y=mx+b, where m is slope and b is the y-intercept

Answer 4

Sooo.. Would it be A?

Answer 5

Or would it be C?

Answer 6

#1 is B

Answer 7

And #2 is D

Answer 8

I need help with Question 3.

Answer 9

#3 is A, because first set up the equation in the proper form: y=mx+b (to do this simply solve for distribute and then solve for y)
