Answer 5

So basically, all you have to do is plug x in to see which one is correct.
Let's try A.
y = 0.4x
So, we'd plug in x and y.
5 = 0.4(2)
5 = .0.8 No. So we can cross A out because it's not true.
Let's try B.
y = 10x
5 = 10(2)
5 = 20 No. So we can cross B out.
Let's try C.
y = 2.5x
5 = 2.5(2)
5 = 5 Yes.
15 = 2.5(6)
15 = 15 Yes.
45 = 2.5(18)
45 = 45 Yes.

Your answer is C.
