6-19.

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.*6-19 HW eTool*(Desmos). Homework Help ✎If

*WXYZ*is reflected using the transformation function (*x*→ −*x*,*y*→*y*) to form*W*′*X*′*Y*′*Z*′, then where is*Y*′?Name a sequence of at least two rigid transformations that will take

*W*′*X*′*Y*′*Z*′ back on to*WXYZ*.

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

Use the eTool to explore various transformations for part (b).
