I've written everything you need in this file, simply download it and tell me if you have any more queries.

In some formulae, the letter 'k' represents the scale factor of the transformation. Simply input the scale factor you've found previously.

Good luck

do we not have to know 'rotation 270 clockwise/anticlockwise' or 'rotation 90 anti clockwise' or 'rotation 180 anticlockwise?'

No, you don't need to know about 270 degrees, and a 180 degree turn will always result in the same position, no matter which direction you turn it. I've already given 90 degrees anti-clockwise, and for clockwise, just make the '1' in the first column negative and the '1' in the second column positive.
It's as easy as that
