Write the slope of the line whose inclination is:
`45^@`

Answer

To find the slope of the line whose inclination is \(45^\circ\), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the angle of inclination**:
We are given that the angle of inclination, denoted as \(\theta\), is \(45^\circ\).

\[ \theta = 45^\circ \]

2. **Use the formula for slope**:
The slope \(m\) of a line is defined as the tangent of the angle of inclination. Therefore, we can express the slope as:

\[ m = \tan(\theta) \]

3. **Substitute the value of \(\theta\)**:
Now, we substitute the value of \(\theta\) into the slope formula:

\[ m = \tan(45^\circ) \]

4. **Calculate \(\tan(45^\circ)\)**:
We know from trigonometric values that:

\[ \tan(45^\circ) = 1 \]

5. **Conclusion**:
Therefore, the slope of the line whose inclination is \(45^\circ\) is:

\[ m = 1 \]

### Final Answer:
The slope of the line is \(1\).
