Well I don't know. Let's find out.

When you say (3,13), that means 'x' is 3 and 'y' is 13.
We'll plug those into the equation, and see if the equation is a true statement.

y = 4x

13 = 4 (3)

4 (3) means 4 x 3, and that's 12.

So the equation says 13 = 12 .

Is that a true statement ?
I don't think so.

So (3, 13) is NOT a solution of y = 4x
