Question

Triangle DEF, shown below, is reflected over the y-axis to form triangle D'E'F'. What are

the coordinates of F'?
(4,6)
(6,4)
(-4, -6)
(-6, -4)

Answer 1

(-6, -4).

Explanation:

When you reflect coordinates over the y-axis, the x-coordinates remain the same, but the y-coordinates become their additive inverse.

The original coordinates for F are (6, -4).

The new coordinates for F would be F' (-6, -4).
