Reflecting over the x-Axis
Triangle ABC has vertices A(-2, 3), B(0, 3), and C(-1,-1). Find the coordinates of the image after a reflection over
the x-axis.
A
B'
C'

Answer 1

Check the picture below.

Answer 2

A'= (-2,-3)

B'=(0,-3)

C'=(-1,1)

Explanation:

coordinates reflected over the x axis follow the rule (x,y) becomes (x,-y). so just multiply each y coordinate by -1 to find the reflected coordinate
