(1) You can observe two lines in the graph. Therefore, it is a System of Linear equations.
Since the lines are intersecting each other, then the System of equations has one solution.
The point of intersection is the solution of the System of equations. Knowing this, you can identify it and label it on the graph.
(2) Based on the explained above, you can identify that the solution to the Linear System is the following:
The answers are:
(1)
(2)
