With the coordinates of (2,10)(4,20)(6,30) on a graph first numbers being the number of sub's on the x axis, and the second number being the cost of the sub's on the y axis. What is the slope-intercept equation for the cost of a sub at Fred's Sub Shop?

A.y=2x
B.y=10x
C.y=5x
D.y=5x+2
Would the answer be D??

Nope

It's C because $5 for 1 sub .. so

y=5x

for 1 it's $5
for 2 it's $10
and on and on.

Thank you so much😀
