In Linear Regression these two variables are related through an equation, where exponent (power) of both these variables is 1. Mathematically a linear relationship represents a straight line when plotted as a graph. A non-linear relationship where the exponent of any variable is not equal to 1 creates a curve.
The functions in Seaborn to find the linear regression relationship is regplot. The below example shows its use.
import seaborn as sb
from matplotlib import pyplot as plt
database = sb.load_dataset('tips')
sb.regplot(x = "total_bill", y = "tip", data = database)
plt.show()Its output is as follows −
