The answer is a) (4,0) hope this helps.
If you multiply -8 and -9 it's 72 because If you multiply two negatives it turns into a positive number/answer and if you add -8 and -9 it's -17.
-8 + -9 = -17
and
-8 * -9 = 72
A circle is a collection of points all of which are on the circumference of the circle. If you use algebra and (x-h)^2 + (y-k)^2 = r^2 and the info contained in the coordinates (x,y) of each city, you can find h, k and r. Then r is the (equal) distance between each city and the center of the circle, where the new tower will be built.
The answer would be A.
If you fill in x for both you would get
y = (3 * 3) - 5
y = 4
y = (4 * 3) - 8
y = 4
