graph the following system x+y=-7, 2x-y=-5

Question

you have to graph the system on like a dotted graph with lines

 

Answer 1

There are two lines; graph each one. The easiest way to graph is often to find both x and y intercepts of lines (this works unless the lines pass through the origin.  Draw the lines carefully on graph paper (also known as Quadrille paper).

 

x intercept is when y = 0 in the equation for the line, and vice versa.
