points on the graph are A at 2,5 B at 6,3

Answer 1

To find the coordinates of points A' and B' after reflecting points A and B across the y-axis, we need to understand how reflection over the y-axis works.

When a point (x, y) is reflected over the y-axis, the x-coordinate changes sign while the y-coordinate remains the same. The new coordinates for the point will be (-x, y).

Let's apply this to the given points:

**Point A:**
- Original coordinates of A: (2, 5)
- Reflecting A over the y-axis:
- New x-coordinate: -2 (change the sign of the x-coordinate)
- y-coordinate remains the same: 5
- Therefore, the reflected point A' is: A' = (-2, 5)

**Point B:**
- Original coordinates of B: (6, 3)
- Reflecting B over the y-axis:
- New x-coordinate: -6 (change the sign of the x-coordinate)
- y-coordinate remains the same: 3
- Therefore, the reflected point B' is: B' = (-6, 3)

In conclusion, after reflecting points A and B in the y-axis:
- The coordinates of A' are (-2, 5)
- The coordinates of B' are (-6, 3)
