Formula:

Where,

Y = LSRL Equation
b = The slope of the regression line
a = The intercept point of the regression line and the y axis.
X̄ = Mean of x values
Ȳ = Mean of y values
SD_x = Standard Deviation of x
SD_y = Standard Deviation of y
r = (NΣxy - ΣxΣy) / sqrt ((NΣx² - (Σx)²) x (NΣy)² - (Σy)²)
