2.Graph the following equations. Then solve the
system using the y=y form of substitution.
Remember you must mathematically solve for
both x and y
EI y = 2x -3
EII y= 3x -7

1. Select the correct set of equations for
this situation and solve them using
substitution.
Solve mathematically here. Hint, if your solution is not the
same as the point on the graph, one of them is WRONG.
