The diagram illustrates an inverting amplifier configuration using an operational amplifier. The circuit is tasked with selecting resistors \( R_1 \) and \( R_2 \) such that the output voltage \( v_o \) equals 7.5 times the source voltage \( v_s \).

### Diagram Explanation:

1. **Voltage Source (\( v_s \))**:
   - Denoted by a circle with a positive and negative sign, indicating the input voltage to the amplifier circuit.

2. **Operational Amplifier**:
   - Depicted by a triangle with a positive (+) and negative (-) input terminal.
   - **Inverting Input (-)**: The line connecting this terminal is linked to the node between \( R_1 \) and \( R_2 \).
   - **Non-inverting Input (+)**: This terminal is connected to the voltage source \( v_s \).

3. **Resistors**:
   - **\( R_1 \)**: Connected between the inverting input and ground.
   - **\( R_2 \)**: Connected between the inverting input and the output of the operational amplifier.
   
4. **Output Voltage (\( v_o \))**:
   - Represented at the output terminal of the operational amplifier.
   - The voltage \( v_o \) is directed towards terminals \( a \) and \( b \), with \( a \) being positive and \( b \) being negative.

### Target Equation:
- The output voltage equation describes the relationship: \( v_o = - \left( \frac{R_2}{R_1} \right) v_s \).
- To achieve \( v_o = 7.5v_s \), the resistances \( R_1 \) and \( R_2 \) must be selected such that \( \frac{R_2}{R_1} = 7.5 \).
