All of the following points lie on the graph of y = 5x except (0,1) (1,5) (2,10) (3,125)

Plug them into the given equation and solve

y = 5x
(0, 1)
1 = 5(0)
1 ≠ 0

y = 5x
(1, 5)
5 = 5(1)
5 = 5

y = 5x
(2, 10)
10 = 5(2)
10 = 10

y = 5x
(3, 125)
125 = 5(3)
125 ≠ 15

The points that do not lie on the graph are the ones that don't equal.
That is point (0, 1) and point (3, 125).

Hope this helps!
