I am really stuck in matrics, I don't know how to find the position vectors like [1 0 0 -1], is there a easy way?

if we look at B to C, the answer is [0 -1, 1 0] but why?

Take the co-ordinates of both the object and image and place them into two matrices, and let x be the required matrix which will take the form
(a b)
(c d)
Solve the matrices to get the required matrix :) Hope it helps.
Cheers
