To find the midpoint \( R \) of segment \( AM \), we need the coordinates of points \( A \) and \( M \). The midpoint formula is:
\[ R = \left( \frac{x_A + x_M}{2}, \frac{y_A + y_M}{2} \right) \]
However, the values for points \( A \) and \( M \) are not provided in your question, so I'm unable to compute the specific midpoint \( R \).
Nonetheless, you can select the correct response corresponding to \( R \) based on your knowledge of those coordinates. The options given are:
- \( R \) is located at \( (-2, 2.5) \)
- \( R \) is located at \( (-2, -2) \)
- \( R \) is located at \( (0, 2.5) \)
- \( R \) is located at \( (-2, 7) \)
If you clarify the coordinates of points \( A \) and \( M \), I can help you determine the correct midpoint \( R \).
