The graph of the system is in the image at the end, the solution is (3, 2).
How to solve the system of equations?
To solve a system of equations graphically, we just need to graph both equations in the same coordinate axis, and then find the point where the graphs intercept.
Here the system is:
y = -1/4x+3
y = 3/4x-1
And you can see the graph in the image at the end.
There we can see that the solution is (3, 2).
