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!

the answer is 31.27mph

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
