We want to find the residual for the given point and line of best fit. We will see that the residual is 0.1
<h3>
How to find the residual?</h3>
The residual is the vertical distance between the experimental points and the adjusting line.
In this case, the line is:
y = 1.1*x + 3.4
And the experimental value is (5, 8.8)
To get the predicted value correspondent to the above one, we need to evaluate the line in the same x-value, so we get:
y = 1.1*5 + 3.4 = 8.9
Then the residual is the absolute value of the difference between the y-values of the experimental value and the predicted value:
|8.8 - 8.9| = 0.1
