Web16 jul. 2024 · Mathematical formula to calculate slope and intercept are given below. Slope = Sxy/Sxx where Sxy and Sxx are sample covariance and sample variance respectively. … WebThe value of 𝑏₁ determines the slope of the estimated regression line. The predicted responses, shown as red squares, are the points on the regression line that correspond to the input values. For example, for the input 𝑥 = 5, the predicted response is 𝑓 (5) = 8.33, which the leftmost red square represents.
