Residual is the difference between values of y. The residual value when x=3 is 0.88 (1-0.12).
What is Residual?
The discrepancy between expected and actual values of y (dependent variable) is the residual for each observation.
Residual = Actual y value − Predicted y
The residual value is the difference between the value of y that is predicted by the function and the value that is actually plotted on the graph.
Now, according to the function, the value of y when the value of x is 3 can be written as,
\(y=2.69x-7.95\\\\y=2.69(3)-7.95\\\\y=8.07-7.95\\\\y=0.12\)
Further, the value of y according to the graph, when the value of x=3 is 1.
Thus, the residual value when x=3 is 0.88 (1-0.12).
