Question

What is the center of the circle that has a diameter whose endpoints are (9, 7) and (-3, -5)?
(6, 6)
(3, 1)
(3, 4)

Answer 1

add the points and divide in half; that gets you the midpoint, the average between the 2

Answer 2

so 9+7and -5+-3

Answer 3

hmm, not adding up the points themselves; but line them up and add them component to component

Answer 4

(9, 7)
+(-3, -5)
---------
(6, 2) then divide those in half

Answer 5

lining them up helps you to keep them in the right order

Answer 6

x+x and y+y

Answer 7

oh ok thanks
