Question

On a coordinate grid, point A is at (−2.0, −3.4) and point B is at (2.0, −3.4). Point B is a reflection of point A across the ___–axis. Input either a lowercase x or y.

Answer 1

Y

Explanation:

Answer 2

y.

Explanation:

When you reflect a point across the x-axis the sign of the y value changes. In the case of reflection across the y-axis the sign of the x value changes. So, for the point A(-2,-3.4) after the reflection the point B(2,-3.4) has the x value with different sign, so is a reflection over the y-axis.
