Choose all of the points that would be on a graph for y=7x
pav-90 [236]
Hey there! :D

Plug in the points to see if they work. 

y=7x

(2,14) -> (x,y)

14=7*2

14=14

That works. 

(0,0) 

0=7*0

0=0

That works 

(1,7)

7=7*1

7=7

That works. 

The points that work are (2,14), (0,0), and (1,7)

I hope this helps!
