Question

What are the coordinates of B

Answer 1

Answer:

(-4,-5)

Step-by-step 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:

$\frac{x + 8}{2} = 2$

rearrange to find x which is -4

work out y coordinate:

$\frac{y + 1}{2} = - 2$

rearrange to find y which is -5

so coordinates are (-4,-5)
