Question

Point A is located at (-2,-1) on the coordinate plane. Point A is reflected over the y-axis to create point A. What ordered pair describes the location of A?

Answer 1

A' (2, - 1 )

Explanation:

under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

A (- 2, 1 ) → A' (-(- 2), - 1) → A' (2, - 1 )
