Question

The cordinate of point A on a grid are (-3,-2). Point A is reflected across the y-axis to obtain part B. The coordinates of point B are (__,-2)

Answer 1

Explanation:

When you reflect a point across the y-axis, the x-coordinate gets multiplied by -1 and the y-coordinate remains the same.

A(-3, -2) => B(3, -2).

The number that is filled in the blank is 3.
