Question

The center of a circle is (4, 6), and an endpoint of a diameter is (2, 5). What is the other endpoint of the diameter?

is it (3, 5.5)? not sure..

Answer 1

Hint: let the other point be (x,y)

This would mean

(x+2)/2 = 4

and

(y+5)/2 = 6

Answer 2

What do you get when you solve (x+2)/2 = 4 for x?

Answer 3

(6, 7)

Answer 4

better, but hopefully you're not guessing

Answer 5

and you can see how you got that answer
