Use gradient multiple to become -1
Then mid pint formula
Find the point and gradient and form equation
For equal distant
Use distance formula since R is on a line, let x and express y in x
Then sub into distant formula
Trick is don’t expand everything
There will be self cancellation
Using xsquare -y square = x-y times x+y
And you will find x and y

I see thank you so much! :)
I forgot Infact we can use the bisector formulae we gotten
Because just solve
Bisector
3x -2y +16=0
Then answer is easier
