How to compute Linear transformation coordinates

[Gaetan593]

Dear all,

I am very confused in regards to Linear Transformation. I’ve seen in the forum that there are some mistakes in the videos, and I am getting really confused.

To get the coordinates, we have to compute the matrix X the vector ? If so, how do I get this result -3 & 4 ?

For me, 3 * -2 + 1 * -2 = -8 and not -3

I am note quite sure that I’ve understood all this topic.

Thanks for your support.

I think I just found at :

(3 * - 2) + (1 * 3) = -3
(1 * -2) 1 (2 * 3) = 4

Am I right ?

Thanks
