In the graph we can see that the two lines intersect at the point (2, -3), in this way, we conclude that the solution to the system of equations is x = 2, y = -3.
How to solve graphically a system of equations?
To solve a system of equations graphically, we need to graph both equations in the same coordinate axis.
The points of intersections between the two graphs are the solutions for the system of equations.
Here, the system is:
y = -x - 1
y = 2x - 7
So we just need to graph these two lines, the graph of the system can be seen in the image below.
In that image we can see that the two lines intersect at the point (2, -3), in this way, we conclude that the solution to the system of equations is x = 2, y = -3.
