Question

Mollie graphs point P(–3, –2). She then graphs the point Q, which is a reflection of point P across the y-axis.

What are the coordinates of point Q?
Responses

A (–3, 2)(–3, 2)

B (3, –2)(3, –2)

C (3, 2)(3, 2)

D (–2, –3)

Answer 1

To find the reflection of point P(–3, –2) across the y-axis, we need to change the sign of the x-coordinate while keeping the y-coordinate the same.

The coordinates of point P are:
- \(x = -3\)
- \(y = -2\)

Reflecting across the y-axis:
- The x-coordinate changes from \(-3\) to \(3\).
- The y-coordinate remains \(-2\).

Therefore, the coordinates of point Q are (3, -2).

So the correct answer is:
**B (3, –2)**.
