QuestionFind the pre-image of vertex A(8,5)A^{\prime}(8,5) after reflection across the yy-axis. Options: (8,6)(-8,-6), (6,8)(-6,8), (8,6)(8,6), (6,8)(6,-8).

Studdy Solution
Calculate the x-coordinate of the pre-image.
Preimage=(8,5)Pre-image = (-8,5)The pre-image of vertex AA^{\prime} is (8,5)(-8,5). However, this option is not listed among the given options. Therefore, there seems to be a mistake in the problem or the given options. The correct pre-image should be (8,5)(-8,5) based on the rules of reflection across the y-axis.
