To reflect a point in the x-axis, we use the same x-coordinate and take the opposite of the y-coordinate.
B
Practice makes perfect
To reflect a point in the x-axis, we use the same x-coordinate and take the opposite of the y-coordinate.
(x,y)
→
(x, - y)
We start from point Y(-3.5,5) and reflect it across the x-axis. So, the resulting point Y' will have the same x-coordinate and opposite y-coordinate.
Y(-3.5,5)
→
Y'(-3.5, -5)
The corrdinates of Y' are (-3.5, -5) so answer B is correct.
