Which point does not lie on the graph of the equation 2x plus y equals 3?

It looks like this came from some multiple choice question, where you're given several choices. Take each choice and substitute the x and y coordinates into the equation. So for example the point is (0,3), then substitute in and get 2*0 + 3 which equals 3 and satisfies the equation, so the point is on the graph. If the point is (1,1) then 2*1 + 1 = 3 which satisfies the equation, so that point is also on the line.

You want to find one where the left side does not equal 3, then that point is not on the graph of the line.
