I won't tell you the answer since this is part of the 8th grade curriculum and it's important but I'll drop some hints
When a shape is rotated clockwise 180 degrees, the coordinates of the first shape go from (x,y) to (-x,-y)
It also goes either up or below.. so it's not the first two options.
You're left with the last two options, and rotating by 270 degrees counterclockwise is
(x,y) becomes (y,-x)
Just do this to QRST and add 1 to x for all QRST coordinates and you will find the answer for one of the choices
