PLEASE HELP ME ASAP!!!! Answer the questions by drawing on the coordinate plane below.(a) Draw the image of after a rotation of 180° about the origin. Label the image .(b) Draw the image of after a reflection across the x-axis. Label the image .

A:
To rotate the figure 180 degrees, you would make it so all the points are:
(x,y) to (-x,-y)
Basically, you would switch every sign on the point.
(1,-1) -> (-1,1)
(3,-2) -> (-3,2)
(3,-4) -> (-3,4)
Those new points would be P'Q'R'.
Then when you reflect over the x-axis, you would flip every y sign.
