Answer:
Both
and
are solutions to the system.
Step-by-step explanation:
In order to determine whether the two given points represent solutions to our system of equations, we must "plug" thos points into both equations and check that the equality remains valid.
Step 1: Plug
into 

The solution verifies the equation.
Step 2: Plug
into 

The solution verifies both equations. Therefore,
is a solution to this system.
Now we must check if the second point is also valid.
Step 3: Plug
into 

Step 4: Plug
into 

The solution verifies both equations. Therefore,
is another solution to this system.
