i knew they were both linear but i need to know where they cross

alternatively, make y the subject of both given equations and make them equal to each other.

Solve both equations simultaneously with some points. You will get your intersection point then.

2x+3y=-3 x-y=-4 2x-2y=-8 5y=5 y=1 x+1=-4 x=-3 x=-3 y=1

start by doubling x-y=-4 and subtract equations

intersection points are y=1 and x=-3 the the graph looks like this |dw:1338929983883:dw|
