Question

point B is 2,4 in quadrant 1 The triangle shown is reflected across the origin. What are the new coordinates of point B?
Responses
A (4, 2)(4, 2)
B (2, 4)(2, 4)
C (-4, -2)(-4, -2)
D (-2, -4)

Answer 1

To find the new coordinates of point B after reflecting it across the origin, you need to change the signs of both the x-coordinate and the y-coordinate.

The original coordinates of point B are (2, 4).

Reflecting this across the origin gives you:
- The x-coordinate: -2
- The y-coordinate: -4

So the new coordinates of point B after the reflection are (-2, -4).

The correct response is:
**D (-2, -4)**.
