GH is a straight line,
The coordinates of G are (-2, 8) The midpoint of GH is (5, -3)
Work out the coordinates of H.

How would you start this question? thank you.

It might help to draw it out so you understand how to work out the H coordinate. The midpoint (M) would be found halfway between G and H, so G -> M is the same change in X and y values as M -> H.

If that doesn't make sense then watch this video and maybe it'll help u understand it better. https://www.mathsgenie.co.uk/mid-point.html

First you need to understand that the midpoint is the same distance from G as it is from H.

Then if you find the distance in the x direction and in the y direction from g to the midpoint and add those distances to the midpoint you'll get H
