Question

Point H(9, 1) is reflected across the x-axis. Which statements about H’ is true?

select each correct answer.

a. the x-coordinate is -9
b. the x-coordinate is 9.
c. the y-coordinate is 1.
d. the y-coordinate is -1.

Answer 1

b and d

Explanation:

Under a reflection in the x - axis

a point (x, y ) → (x, - y ) , then

H (9, 1 ) → H' (9, - 1 )

the x- coordinate is 9 → b

the y- coordinate is - 1 → d
