On graph paper, graph quadrilateral $MNPQ$ if $M(-3,6)$, $N(2,8)$, $P(1,5)$, and $Q(-4,3)$.  

1. What shape is $MNPQ$? Show how you know.

   Hint (a):

   Look at the graph. What kind of quadrilateral is it?

2. Use the function $x→x$, $y→-y$ to reflect $MNPQ$ across the $x\text{-axis}$ and create $M'N'P'Q'$. What are the coordinates of $P'$?
