What is the answer?
### Dilation of Triangle \( \triangle ABC \) on the Coordinate Plane

#### Problem Statement

Khadija draws \( \triangle ABC \) in the coordinate plane. She dilates \( \triangle ABC \) using a scale factor of \(\frac{1}{2}\) with the center of dilation at the origin to form \( \triangle A'B'C' \). She then dilates \( \triangle A'B'C' \) using a scale factor of \(\frac{3}{2}\) with the center of dilation at the origin to form \( \triangle A''B''C'' \).

**Task:** 
What are the coordinates of \( \triangle A''B''C'' \)? Show your work.

#### Explanation of the Graph

- The graph is a coordinate plane with lines marked for both x and y axes.
- \( \triangle ABC \) is plotted with vertices at specific coordinates. The side lengths and orientation of the triangle are visible.

#### Steps to Solve

1. **Dilate \( \triangle ABC \) with scale factor \( \frac{1}{2} \):**
   - Each coordinate of \( \triangle ABC \) is multiplied by \( \frac{1}{2} \) to get \( \triangle A'B'C' \).
   
2. **Dilate \( \triangle A'B'C' \) with scale factor \( \frac{3}{2} \):**
   - Each coordinate of \( \triangle A'B'C' \) is multiplied by \( \frac{3}{2} \) to get \( \triangle A''B''C'' \).

#### Solution

**Calculate the coordinates for each step and obtain the final coordinates for \( \triangle A''B''C'' \).**

- Verify and confirm the steps mathematically to ensure accuracy in plotting the triangles and obtaining the coordinates.
