How do I solve the system of equations by graphing: y=x-5 and -2x +y=-10
----------
You graph the 2 equations.
The intersection is at the values that fit both equations.
----
Both graphs are straight lines, so 2 points are needed.
Pick values for x or y, and find the other variable.
Plot 2 points.
Draw a line thru them.
