Solve this system of equations by graphing. First graph the equations, and then type the solution.
y=x–4
x=3
The first equation is already in slope-intercept form, so we can easily graph it by plotting the y-intercept at -4 and using the slope of 1 to find another point.
The second equation x=3 is a vertical line passing through x=3.
The solution to the system of equations is the point where the two lines intersect. In this case, they intersect at (3, -1).
Therefore, the solution is x=3, y=-1.
