Question

Find the coordinates of the reflected image.

A triangle with vertices F(–1, 9), G(–2, 1), and H(–7, 4) is reflected over the x-axis.

​

Answer 1

see explanation

Explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), hence

F(- 1, 9) → F'(- 1, - 9)

G(- 2, 1) → G'(- 2, - 1)

H(- 7, 4) → H'(- 7, - 4)
