Please help me with this question.

A. -g/-8

Step-by-step explanation:

Since there is a negative sign before the fraction -g/8, A would be the best choice because the negative on the problem given is the same as -g/-8. No matter if there's a negative sign before the fraction, both the denominator and numerator would still be negative.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
