    the first part is a reflection in the y-axis what do you think the second transformation is?

    imagine the y-axis is a mirror - where would the image of ABCD be on the graph/

    yes exactly but in what did it get reflected and what is direction and magnitude of the translation?

    the question also asks you to write the coordinates of the figure after each transformation.

    yes so do i write down the A'B'C'D' coordinates?

    deal with the reflection first - in what axis is it reflected and what are the coordinates of the 4 points?

    umm. it reflects over the y- axis right?

    ok so know i have to right down the coordinates, which are A'(4,0) B'(2,-2) C'(2,-5) and D'(4,-3) right?

    No you need to write the coordinates after the retlection eg A (4,-4) goes to A' ( 4,4)

    A(-4,4) to A'(4,0), B(-2,2) to B'(2,-2), C(-2,-1) to C'(2,-5), D(-4,1) to D'(4,-3). Did i do this right @welshfella ?

    No you have not written to coordinates of the image formed after the first transformation which was the reflection you have missed that part out

    the coordinates are correct for the FINAL IMAGE - but you need to write the ones for the intermediate image as well.
