Question

Find the location of the center of a circle if the endpoints of the diameter are at (-10,

-5) and (8,4).

Answer 1

(- 1, -
`(1)/(2)` )

Explanation:

The centre is located at the midpoint of the diameter.

Using the midpoint formula , then

centre =
`(-10+8)/(2)`,
`(-5+4)/(2)` ) = (
`(-2)/(2)`,
`(-1)/(2)` ) = (- 1, -
`(1)/(2)` )
