Hi please help im honestly so tired and I don't have the time to constantly read this so I can get it

ANSWER: 3

image at the bottom to help you visualize!

First, Let's graph point A:

( The red point )

Now reflect point a across the X axis which is the horizontal line (to get point B):

( The blue point )

We see that --> in the point (5,-3), the y coordinate, (-3) changed to (3)

SO THE ANSWER WOULD BE: 3

Summary:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed).

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).

HOPE THIS HELPS!
