Sorry about the handwriting! For (ii), since the distance AB:CD is 3:7, we can conclude that the x coordinate for C must be -2+7. Since C and D share the same y coordinate, they must be the same. For (iii), since we already have values for the base and height of the triangle, finding an exact coordinate for P is redundant. Hope this helps!
