Hi,

"I have to graph this but cannot make a graph."

1. need two points to connect to draw a graph of a Line...

3x-y=0   This line has (x,y) ordered pairs: (0,0)when x = 0     and (1,3)when x= 1

2x-y=-1  This line has (x,y) ordered pairs: (0,1)when x = 0     and (-1/2,0)when y =0

2 . Plotting these (x,y) ordered pairs and connecting with their respective Lines

3.  We find the lines intersect at (x,y) ordered pair (1,3)

4. Ordered Pair (1,3) is the solution for this system of EQs
