Question

Pls help really fast I don't know this!!!!!

Answer 1

I think it's (3,4) but I am not confident so please be understanding

Answer 2

(3, 1 )

Explanation:

The centre of the circle is at the midpoint of the diameter.

Given endpoint (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

(
`(x_(1)+x_(2) )/(2)` ,
`(y_(1)+y_(2) )/(2)` )

Here (x₁, y₁ ) = (9, 7) and (x₂, y₂ ) = (- 3, - 5 ) , then

midpoint = (
`(9-3)/(2)`,
`(7-5)/(2)` ) = (
`(6)/(2)`,
`(2)/(2)` ) = (3, 1 )

Thus centre of circle = (3, 1 )
