Question

C. Triangle GHJ with coordinates G(2, -9), H (3,8), and J (1,6) is reflected across the x-axis.

Answer 1

Reflection of (x, y) over x-axis is (x, -y)

If triangle GHJ with coordinates G(2, -9), H (3,8), and J (1,6) is reflected across the x-axis, the coordinated becomes

G' ( 2, 9)

H'( 3, -8)

J' (1, -6)
