Using the graph we can estimate the solution of the system as (-3, 1.5)
How to estimate the solution for the system of equations?
When we want to solve a system of equations graphically, we need to graph both equations in the same coordinate axis.
Once we do that, we need to try to identify where do the graphs intercept, that intercept point will be the solution of the system of equations.
Here we can see that the lines intercept at x = -3 and y = 1.5, so we can estimate that the solution is (-3, 1.5)
