Question

figure abcde was reflected across the line y = x to create figure abcde. what are the coordinates of the pre - image of e?

Explanation:

Step1: Recall reflection rule

When reflecting a point across the line $y = x$, the coordinates $(x,y)$ of the pre - image and $(y,x)$ of the image are swapped.

Step2: Identify coordinates of $E'$

From the graph, assume the coordinates of $E'$ are $(5,-2)$.

Step3: Find pre - image coordinates

Swapping the $x$ and $y$ coordinates of $E'$, the pre - image of $E'$ has coordinates $(-2,5)$.

Answer:

$(-2,5)$
