Question

trapezoid lmnp was reflected using the rule $r_{y - axis}(x,y)\to(-x,y)$. which figure represents the image of the reflection? figure a b c d

Explanation:

Step1: Understand reflection rule

The rule $r_{y - axis}(x,y)\to(-x,y)$ means reflection over the y - axis. Points on the left of the y - axis will move to the right and vice - versa, while the y - coordinates remain the same.

Step2: Analyze trapezoid LMNP

Trapezoid LMNP is on the left - hand side of the y - axis. After reflection over the y - axis, its image will be on the right - hand side of the y - axis with the same shape and size, and the y - coordinates of its vertices unchanged.

Answer:

The figure that represents the image of the reflection is the one that is the mirror image of trapezoid LMNP across the y - axis. Without seeing the full content of figures A, B, C, D clearly in the image provided, in general, the reflected trapezoid will have the same height (y - values) for corresponding vertices and the x - values will be the opposite of the original x - values. If we assume the figures are arranged such that one of them is the correct mirror - image across the y - axis, we need to check which figure has vertices with coordinates $(x,y)$ of the original trapezoid transformed to $(-x,y)$.
