How to Draw Line of Linear Regression in Python

In this example we will show how to draw the line of Linear Regression in Python.

Source Code

import matplotlib.pyplot as plt
from scipy import stats

x = [14.4, 16.5, 11.9, 15.4, 18.6, 22.2, 19.5, 25.3, 23.4, 18.2, 22.6, 17.4]
y = [225, 334, 192, 339, 411, 530, 418, 623, 551, 430, 452, 416]

slope, intercept, r_value, p_value, std_err = stats.linregress(x, y)

# Defines an object that contains linear equations
def myfunc(x):
    return intercept + slope * x

# The value of x on the y-axis
mymodel = list(map(myfunc, x))

plt.scatter(x, y, label='original data')
plt.plot(x, mymodel, 'r', label='fitted line')
plt.legend()
plt.show()

Output:
