Never mind, I got it. Simultaneous equations.
Given that a linear transformation moves points (1,0) and (2,-3) to (2,-1) and (1,3), respectively, determine the image of point (-3,6).
I don't get the first step to the solution.
[Sol] Letting (-3,6) =k(1,0)+L(2,-3)
k=1, L=-2
How do you know what k and L is?
