Answer:
To reflect a point, you need to find the exact point of each corner of the figure. The first point could be say, -5, -1. You know that you go 5 points to the left to get to the line so you go another 5 points to the left from the line. So basically find the opposite of each number, so -5, -1 so it becomes 5, 1.
The next point would be -5, -6 so it becomes 5, 6.
-7, -5 turns into 7, 5.
Plot all of the points and it should look like this graph below.
