and S(3, -3). Which coordinate below would represent R' if
point R was reflected across the x-axis?
A. (-8, 3)
B. (3, 3)
C. (8, -3)
D. (-3,-3)

Answer 1

If point R is reflected across the x-axis, its y-coordinate will change sign. Therefore, the y-coordinate of R' will be 3 (the opposite of -3). Thus, the answer is A. (-8, 3)
