To use Matplotlib's pyplot library to make a line plot, you would first need to import the library with the following code:
```
import matplotlib.pyplot as plt
```
Next, you would need to define your data as x and y values in Python. For example, if you wanted to plot the points (1, 2), (2, 4), (3, 6), and (4, 8), you would define them like this:
```
x = [1, 2, 3, 4]
y = [2, 4, 6, 8]
```
Then, you would use the `plot` function to create the line plot:
```
plt.plot(x, y)
```
Finally, you can use various functions from the library to customize your plot, such as `xlabel`, `ylabel`, `title`, `legend`, or `grid`.
```
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.title('Line Plot Example')
plt.grid(True)
plt.show()
```
