Given a system of equations:
We have to graph the system of equations.
Find two points that lie on the first equation. y = -x + 3.
Here, if x = 3, then y = 0, and if x = 0, then y = 3.
Find two points that lie on the first equation, y = 1/3 x + 7.
Here, if x = -21, then y = 0, and if x = 0, then y = 7.
Now plot these points on the graph and join them.
