(5,-1) is located in quadrant IV......quadrant IV has (+ x, -y).....so any points that have (+ x, - y) are in this quadrant.
Example : (6,-3) is in this quadrant......(2,-4) is also in this quadrant.
So whoever has the house with (+ x, -y) is going to be in the same quadrant as the community center.
The answer would be 34.8 I’m pretty sure
61 degrees, hope this helps!
