Question

PLEASE HELP NOW!

The coordinates of point A on a coordinate grid are (−2, −3). Point A is reflected across the y-axis to obtain point B and across the x-axis to obtain point C. What are the coordinates of points B and C?


B(2, 3) and, C(−2, −3)

B(−2, −3) and C(2, 3)

B(2, −3) and C(−2, 3)

B(−2, 3) and C(2, −3)

Answer 1

1. Point B.

If you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate changes into its opposite. So, if we have a point, the reflection of this point across the x-axis is the point. Finally, our point A (-2,-3) changes into:

Point B: (-2,3)

2. Point C.

If you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate changes into its opposite. So, if we have a point, the reflection of this point across the y-axis is the point (-x,y) . Finally, our point A(-2,-3) changes into:

Point C:(2,-3)
