I added you :) I hope you don’t mind
An easy way to find an endpoint when the midpoint is given is to simply count the distance from the given endpoint to the midpoint, and go that distance from the midpoint in the opposite direction of the other endpoint. Using your problem as an example:
The y value doesn't change, so we only need to worry about x.
From 1 to -4, you go left 5 (-4 - 1 = -5). So, do that again, and you get -9.
Therefore, the coordinates of the other endpoint are (-9, -2), or B.

Answer:
The cost for painting will be $212.
Step-by-step explanation:
I am painting the walls and ceiling of a rectangular 20 x 30 ft room. The walls are 10 feet tall.
So, the total area to be painted = {2 × (20 + 30) × 10} + (20 × 30) = 1600 sq. ft.
Now, a gallon of paint covers 400 square feet and cost $53 per gallon.
So, the number of gallons of paint required will be 
gallons.
And the cost for painting will be $(4 × 53) = $212. (Answer)
