Question

23. What would be the location of the vertex (3, 4) if it were reflected across

the y-axis?
A. (3,-4)
B. (-3, 4)
C. (4, -3)
D. (-4, 3)

Answer 1

Answer is B. ( -3, 4)
Reason

The rule for a reflection over the y -axis is (x,y)→(−x,y) . So from x to -x (-3) and y stays the same (4)

Answer 2

The answer is B. (-3,4) as it is being flipped across the y-axis, so only the y-coordinate is being changed.

I hope that this helps! :)
