You can put this solution on YOUR website!
Plug x in the equation and if you get the same y, then it's on the graph.
(5/2, 3)
2x+-+%282%2F3%29y=3
2%2A%285%2F2%29-%282%2F3%29y=3
5-%282%2F3%29y=3
-%282%2F3%29y=-2
y=3
Since the y matches the y in the order pair then it is on the graph.
Now do the same with (3/2, 20).
