Please, look this attach file.

Answer 2

Thank you so much.
I have another question how do you graph equations in that format ?

Answer 3

Is there a formula?

Answer 4

no, there isn't a formula, only you must plot (draw) each function. See, for example, "x+y=0" is the same thing that y=-x and "x-y+2=0" is y=x+2, and (-1,1) is the intersection point of two function. Understood? Sorry my english, please.
