Question

On a coordinate grid, both point (3,5) and point (-2,-4) are reflected across the y-axis. What are the coordinates of the reflected point?

A. (-3,5) and (2,4)
B. (-3,5) and (2,-4)
C. (-3,-5) and (-2,-4)
D. (3,-5) and (-2,-4)

Answer 1

When a point is reflected across the y-axis, the x-coordinate changes sign while the y-coordinate remains the same.

Step-by-step explanation:

When a point is reflected across the y-axis, the x-coordinate changes sign while the y-coordinate remains the same. So, the coordinates of (3,5) after reflecting across the y-axis would be (-3,5). Similarly, the coordinates of (-2,-4) after reflecting across the y-axis would be (2,-4).

Therefore, the correct answer is Option D: (3,-5) and (-2,-4).
