Question

What is the center of the circle that has a diameter whose endpoints are (6, -4) and (18, 10)?


(12, 7)

(12, 6)

(12, 3)

Answer 1

(12,3)

Answer 2

All I did was graph the points, then I found the center.

Answer 3

Okay, one more question.

Answer 4

What is the center of the circle that has a diameter whose endpoints are (-3, -5) and (-11, -7)?


(-8, -1)

(-7, -6)

(-4, -6)

Answer 5

\[\frac{ (x _{1}+x _{2}) }{ 2 },\frac{ y _{1}+y _{2} }{ 2 }\]

(x1,y1)= (6, -4)
(x2,y2)=(18, 10)

\[\frac{ 6+18 }{ 2 },\frac{ -4+10 }{ 2 }\]

\[\frac{ 24 }{ 2 },\frac{ 6 }{ 2 }\]

\[12,3\]

Answer 6

Same formula u apply in second question

Answer 7

(-7, -6), I did the same thing. I plotted the points, and then I found the center. I always double check using rise over run.
