What are my residuals for this scatter plot? And how do i create a residual plot?

A residual is the difference between what is plotted in your scatter plot at a specific point, and what the regression equation predicts "should be plotted" at this specific point. ... A residual is the difference between the observed y-value (from scatter plot) and the predicted y-value (from regression equation line).

Step-by-step explanation:

Residual Plot. A residual plot is a graph that shows the residuals on the vertical axis and the independent variable on the horizontal axis. ... The first plot shows a random pattern, indicating a good fit for a linear model.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
