um, why did you do that?
this maths challenge isn't very extreme... I was disappointed. wait till you get to ext2 maths

umm i used midpoint theorem because yz is the diameter and we also have the centre which is the midpoint of the radius soooo......

A quicker way is by observation where Y is 5 units below the centre, thus Z must be 5 units above the center which is (-1, 3).

Thus Z is (-1,8)
