Q:

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 .

Accepted Solution

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.

(-1,1) -> (-1,-1)

(-3,2) -> (-3,-2)

(3,-4) -> (3,4)

You would chart those points as P"Q" R".

I hope this helps! (review my answers)

Sorry this took so long!
