Answer:



Explanation:
The solutions to a graphed system of equations can be found at the points where the graphs of the equations intersect.

Given system of equations:

From observation of the given graph of this system of equations, there are no solutions, as there are no points of intersection.

Given system of equations:

For this graphed system of equations, there are 2 solutions as there are 2 points of intersection.
From observation of the given graph, the points of intersection are:

Given system of equations:

For this graphed system of equations, there is one solution as there is one point of intersection.
From observation of the given graph, the point of intersection is:
