Step-by-step explanation: we have the first transformation as follows
As we can see above we have the original coordinates on the left and then we translate all points 3 units to the left and 4 units down on the centre to obtain the coordinates on the right.
Now we can rotate our points as follows
As we can see above, to rotate 180° we just need to change the signs of the coordinate of the points.
Finally, we can draw the final points as follows
