Question

The point (1, -5) is reflected across the y-axis. What are its new coordinates?

A: (-1, -5)
B: (1, 5)
C: (-1, 5)
D: (1, -5)

Answer 1

The new coordinates of the point (1, -5) after reflecting across the y-axis are (-1, -5).

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. In this case, the original coordinates of the point are (1, -5). So when the point is reflected across the y-axis, the new coordinates will be (-1, -5).
