Two points define a line. Then, we can take two values of x and replace them in each equation to get their respective y-coordinates.
Equation 1
Now we can graph and connect the points to obtain the graph of this line:
Equation 2
Now we can graph and connect the points to obtain the graph of this line:
Finally, the solution of the system is the point at which the lines intersect:
Therefore, the solution of the system is
