Regression Formula :

Regression Equation(y) = a + mx
Slope(m) = (N x Î£XY - (Î£X_m)(Î£Y_m)) / (N x Î£X² - (Î£X)²)
Intercept(a) = (Î£Y_m - b(Î£X_m))

Where,

x and y are the variables.
m = The slope of the regression line
a = The intercept point of the regression line and the y axis.
N = Number of values or elements
X = First Data Set
Y = Second Data Set
Î£XY = Sum of the Product of First and Second Data Set
Î£X_m = Mean of First (X) Data Set
Î£Y_m = Sum of Second (Y) Data Set
Î£X² = Sum of Square of First (X) Data Set Values
