Answer 1

What is the center of the circle that has a diameter whose endpoints are (-3, -5) and
(-11, -7)?
My answer is (-8, -1) But i'm not sure if it's right

Answer 2

So first, you have to find the Δx and Δy for this equation.
-11 - (-3) = -8 Δx
-7 - (-5) = -2Δy
Divide by two to find the endpoints
-8/2 = -4 for x
-2/2 = -1 for y
(-4,-1)

Answer 3

I hope I didn't mess up on your last question, I just realized my mistake, can you pot it here again?

Answer 4

My previous one?



Actually wait i dont' have (-4,-1) asmy choice /:

Answer 5

Oops, I forgot a step, (-4,-1) is what you add to the lower coordinate (-3,-5), so the midpoint should be (-7,-6)

Answer 6

I'm solving it two different ways Q_Q, I'm sorry.

Answer 7

I can see that you're having a confusion xP

Answer 8

You can also do it the other way (which I deleted since for some reason I thought it was wrong).

Answer 9

-11+-3 = -14 for x
-7 + -4 = -12 for y
Divide by two
-14/2 = -7
-12/2 = -6
(-7,-6)

Haha, I was doing it right the whole time oops.

Answer 10

Accidentally took a different route.

Answer 11

Haha das fine with me xP
