Solve the following system of equations graphically without using a calculator:
In order to solve the system of equations graphically, we need to draw the lines. Since the first equation is already written in the , we only need to rewrite the second one.
Now, we can draw the lines in a coordinate system by interpreting the lines' , and .
The intersection point for the lines is
-values which solve the equation system.
The lines' point of intersection is
. So the equation system has the solution
