WebIdentify and interpret the y-intercept. The y-intercept is 6.5. When $x=0$ the predicted value of y is 6.5. Identify and interpret the slope. The slope is 1.8. For every one unit increase in x, the predicted value of y increases by 1.8. Compute and interpret the residual for the point (-0.2, 5.1). WebThe predicted value is denoted by The predicted value is determined from the regression equation which is defined as: Here, a is the y -intercept, b is the slope and is the independent variable. For example - suppose a regression model for the body fat percentage based on body mass index.
