Answer 2

You can look at the points and see which ones gives you the result you desire. For example, if you put 1 in for x, only one of the functions will have an output of 9 for y, which is what you are looking for.

Answer 3

oh okay @blurbendy

Answer 4

so it's E?

Answer 5

do you see which one it is?

Answer 6

Yes, good job!

Answer 7

alternate way :
you can use the equation of line through origin as
y=mx
since (1,9) lies on line , plug in x=1, y=9 to get 'm'.
