You can put this solution on YOUR website! On a coordinate plane, graph the system of equations y = - 2x and y = 2x + 3.
----------------------
Each graph is a straight line, so you need 2 points.
y = -2x
Pick 2 values for x and find y.
x = 0, y = 0 --> (0,0) Plot the point
x = 5, y = -10 --> (5,-10) Plot the point
Draw a line thru them
-----------------
Do the same with the other equation.
