Like I said, draw the unit vectors and see what happens to them.

So, if (1 0) gets mapped to (ab)\begin{pmatrix}a \\ b\end{pmatrix} and (01)(0 1) gets mapped to some other point. Then you can write down (a... b...)\begin{pmatrix} a & ... \ b & ...\end{pmatrix}. Look up the examsolutions video for more detail.

Just look it up under FP1 edexcel matrix transformations.
