a transition of 7 units right shifts it completely to the right side of the y axis.
a transition then of 5 units down shifts it completely into the second quadrant (positive x, negative y). it is now completely below the x axis and right of the y axis.
and now a reflection across the y axis keeps it below the x axis but shifts it completely to the left of the y axis. and it is therefore more in the third quadrant (negative x, negative y).
