Question

What are the new values of (a) , (b) and (c)

The problem involves a point \( (-1, \frac{3\pi}{2}) \) given in polar coordinates. The goal is to find other polar coordinates \( (r, \theta) \) for the same point that satisfy certain conditions.

### Instructions:

1. Choose the graph that correctly plots the point \( (-1, \frac{3\pi}{2}) \).

2. For the same point on the graph, find new values of \( (r, \theta) \) for which:
   - \( r > 0 \), \( -2\pi \leq \theta < 0 \)

### Choices:
- **Graph A:** 
  - Circle with an arrow pointing to the left.
  - Labeled angles: \( +x \), \( +y \).
  
- **Graph B:** *(Highlighted as Correct)*
  - Circle with an arrow pointing vertically downwards.
  - Labeled angles: \( +x \), \( -y \).

- **Graph C:** 
  - Circle with an arrow pointing upwards.
  - Labeled angles: \( -x \), \( -y \).

- **Graph D:** 
  - Circle with an arrow pointing upwards.
  - Labeled angles: \( +x \), \( +y \).

### Additional Notes:

- The polar coordinates \( (-1, \frac{3\pi}{2}) \) are to be interpreted on the standard polar coordinate plane.
- The objective is to manipulate the coordinates while adhering to the given conditions for \( r \) and \( \theta \).
