 Question 23305: How do you know how to plug the point onto the graph. For example if the equation is 2x+3=7 the answer will be x=2. How do you plug that in without a y, because if there is an x there needs to be a y, but the answer just ends up x=2.Answer by stanbon(57967)   (Show Source): You can put this solution on YOUR website!That's correct, x=2. So the graph is all points that have x=2. So it includes (2,3), (2,7) and every other point that has x-=2. Cheers, Stan H.
