The point S (-1,-3) is reflected across the line y=-2

======================================================

Explanation:

Refer to the diagram below.

The point S(-1,-3) is exactly 1 unit below the line y = -2.

Move up 1 unit to go from S to a point on the line, and directly above S.

Then move another unit up to arrive at S ' (-1, -1) which is the result of reflecting point S(-1,-3) over the line y = -2.

Both S and S' are the same distance away from the mirror line y = -2.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

answer: the answer is 110
