Answer:
6
Step-by-step explanation:
The center of the circle is the midpoint of the diameter. The midpoint can be found by averaging the coordinates of the end points:
((-4, 2) +(12, 10))/2 = ((-4+12)/2, (2+10)/2) = (4, 6)
The y-coordinate of the center is 6.
Answer:
x = -6
Step-by-step explanation:
6x + 6 = -30
Subtract 6 from each side
6x + 6-6 = -30-6
6x = -36
Divide each side by 6
6x/6 = -36/6
x = -6
