Answer:
P'(-3, -2), Q'(-2, -4), and R'(8, 4)
Explanation:
To reflect across the line y = x, we can use the following rule:
(x, y) ----> (y, x)
Therefore, the coordinates of the vertices in the image reflected will be:
(x, y) ----> (y, x)
P(-2, -3) ----> P'(-3, -2)
Q(-4, -2) ----> Q'(-2, -4)
R(4, 8) ------> R'(8, 4)
So, the answer is:
P'(-3, -2), Q'(-2, -4), and R'(8, 4)
