okay I get it but why the fuck would anyone want to do this

if im writing a program, i would much fucking rather just have a transformation function that just maps [x,y] -> [x+h,y+k] directly.
something like r(x,y,h,k){ return [x+h,y+k]; } I mean.

why the hell would I want to have to compute a matrix multiplication? isn't that much more work than what's necessary? what the fuck is the point
