Answer 1

To perform a dilation centered at the origin with a scale factor of 2, you multiply each coordinate of the vertices by the scale factor.

Given the points:

• \( P(-3, -3) \)
• \( Q(2, -3) \)
• \( R(-2, -2) \)

Now, let's apply the dilation:

1. For point \( P' \): \[ P' = (2 \times -3, 2 \times -3) = (-6, -6) \]

2. For point \( Q' \): \[ Q' = (2 \times 2, 2 \times -3) = (4, -6) \]

3. For point \( R' \): \[ R' = (2 \times -2, 2 \times -2) = (-4, -4) \]

So, the coordinates of the vertices after the dilation are:

• \( P'(-6, -6) \)
• \( Q'(4, -6) \)
• \( R'(-4, -4) \)
