Which graph does NOT represent y as a function of x?

The graph of a quadrilateral is shown. The quadrilateral will be transformed using the rule (x, y) ---> (-y, x). Which graph represents the quadrilateral after the transformation?

A figure is graphed on a coordinate grid. Point P on the figure is located at (-2, 8). The figure is translated m units right and t units down. Which rule describes P' after the translation? Options: (x, y) --> (-2 - m, 8 - t), (x, y) --> (-2 + m, 8 + t), (x, y) --> (-2 - m, 8 + t), (x, y) --> (-2 + m, 8 - t)
