Webb4.3 - Residuals vs. Predictor Plot. An alternative to the residuals vs. fits plot is a " residuals vs. predictor plot ." It is a scatter plot of residuals on the y axis and the predictor ( x) values on the x axis. For a simple linear regression model, if the predictor on the x axis is the same predictor that is used in the regression model, the ... WebbIts pretty simple from there. So, we know in the slope intercept formula (y=mx+b) we know that m=slope and b=y intercept. So for the equation I gave you m=1/4 and b=2. So, from the y-intercept (which is 2) you move 4 spaces to the right and 1 space up. Hope that helps!:) Comment ( 4 votes) Upvote Downvote Flag more Show more...
