A) The graph accurately graphs quadrilateral WXYZ.
B) Just multiply the x-values of the points by -1 and re-graph the quadrilateral with the new values. I'll do it for you:
W: (2,-2)
X: (-3,1)
Y: (-5,-1)
Z: (-4,-6)
I even graphed it for you using desmos: (I've attached it.)
C) I think they want to you to answer the question using the new graph I just graphed. So the line that is congruent to YZ would be Y'Z'. (The " ' " is used to show a congruent figure.) The other three figures are done the same way with XY congruent to X'Y', WX congruent to W'X', and ZW congruent to Z'W'.
D) You can find the angle x by calculating the slope of XY and XW but I don't think that's what the question means. But you can take the easy way out and say that angle x is congruent to angle x'. Similarly, angle w is congruent to angle w', angle y is congruent to angle y', and angle z is congruent to angle z'.
