All you need to do is Plug the Y axis into y and the x axis into x like this 
0y-3=3(3)

anonymous · Answer

Actually you are going to want to think of your x values as the input and y as the output. When solving for this problem plug the x values in for x and then solve for y. If y corresponds to the output given, then you know that x is valid.

so for the first example: (0,3)
y-3=3x
y-3=3(0)
y-3=0
y=3
