Question

1. What is the slope-intercept for the cost of a sub at Fred’s Sub shop?

A- y=2x
B- y=10x
C- y=5x
D- y=5x+2

Answer 1

Answer:the answer is A.

Explanation:

Plug in 1 in replace of X. Then you multiply the number that was originally next to X by 1 and then if it’s added to another number for an example 5x+2 turns into 5(1)+2 next 5 multiplied by 1 is 5. 5+2 =7. It cannot be 7 because your red line doesn’t extend out that far.

Answer 2

The answer is C. Simple explanation is to divide y by x, so for example: 10/2 = 5 and 20/4 =5.
