On graph paper, plot and connect the points to form trapezoid $WXYZ$ if its vertices are $W(7, 3)$, $X(4, 3)$, $Y(1, 9)$, and $Z(6, 5)$. Remember that a trapezoid is a $4$-sided figure (quadrilateral) with at least one pair of parallel sides. .  

1. If $WXYZ$ is reflected using the transformation function ($x → −x$, $y → y$) to form $W′X′Y′Z′$, then where is $Y′$?

   Hint (a):

   Transform each point according to the transformation function. For $W$ this would be: ($7 → −7$, $3 → 3$) so $W^{'}$becomes $(−7, 3)$.

2. Name a sequence of at least two rigid transformations that will take $W′X′Y′Z′$ back on to $WXYZ$.
