hi DarkTangent

First draw a diagram. Then make use of some tracing paper. In the UK in GCSE exams, tracing paper is allowed.

That answer is not correct. The method looked right though.

hi Dark Tangent

I get this:

Q (2,7) rotates to Q' ((0,5) and then reflects to (2,5)

thickhead wrote:

So the coordinates of various points will be N(0,-4) ,P( 2,-4) and Q(2,0).

Is this correct? The rotation is 270 clockwise.

You can either find the midpoint of and perform the translation, or translate and then determine the midpoint.

I overlooked "clockwise". My answer is for counterclockwise 270 degrees rotation.
