Okay, wow I didn't know that the link to the graph was sooo long I'm sorry... here is what my teacher said about my graph~
"1st line graphed correctly; 2nd is not"

Answer 3

@mathmale could you try to help me? please?

Answer 4

If x-y=0, x=y or y=x. Sketch the graph.

If 3x+y=-4, solve for y. y=-3x-4. Sketch this on the same set of coordinate axes as you did y=x. Identify the point at which the 2 graphs intersect. Use the draw utility if you wish .
