I NEED HELP PLEASE, THANKS! :)

Point A(-5,8) is reflected across the line y=x. What are the coordinates of A'? Show your work and explain.

Let's say we have the point (x, y). If the point were to be reflected across the line y = x, then the new coordinate will basically switch the order if the numbers.

(x, y) → (y, x)

In the question, we are given the point (-5, 8). Since the order of the numbers get switched, we get the final product of (8, -5).

Best of Luck!

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
