Gradient of regression calculator

WebWe first calculate the slope through the formula, m= r (σ y /σ x ) Once we have done this, then we can calculate the y-intercept. We do this by multiplying the slope by x. We then subtract this value from y. This is the y-intercept. With the slope and y-intercept calculated, we then can have our regression line.
