The problem states: Lines y = 3 + 2/3x, y =-1/3x, and y = -4/3x +3 intersect to form a triangle. Find the verticies. I solved for x by substituting x for y, then I solved for y and started to plot the lines on a graph. I get a constant value for x, and different values for y, which doesn't form a triangle. Did I do the wrong thing?

Without seeing what you got or how, it's hard to say. But you might want to start with the fact that the corners of the triangle are where pairs of lines cross.
