Can someone please he me with part a. I think I can do part b and c by myself, once i know how to do part a...

Find the gradient of line AB first.
The gradient off perpendicular bisector is =-1/ gradient of AB.

Through y=mx+c,
U can now find the equation of the perpendicular bisector!

Hope this helps!
