Question

What are the coordinates of B

Answer 1

(-4,-5)

Explanation:

The coordinates of the midpoint for x = sum of x/2=2

The coordinates of the midpoint for y = sum of y/2=-2

firstly to work out x coordinate:

`(x + 8)/(2) = 2`

rearrange to find x which is -4

work out y coordinate:

`(y + 1)/(2) = - 2`

rearrange to find y which is -5

so coordinates are (-4,-5)
