Question

45) lí the midpoint of AB is (4,3) and point A has coordinates (-2,6),

what are the coordinates of point B?

Answer 1

Midpoint has a formula x plus x2 divided by 2 and vice versa for y
So to solve you need to fill in numbers
You can replace x with negative 2 since you know that the coordinates for point A are -2,4
Solve to get 10
And vice versa for the y coordinate you solve the filled in equation to get 0
Your end result is 10,0
