Answer:
True
Step-by-step explanation:
The residual value will be equal to -1.
<h3>What is residual value?</h3>
A residual is a difference between the observed y-value of a data point and the predicted y-value on a regression line for the x-coordinate of the data point. A residual is positive when the point is above the line, negative when it is below the line, and zero when the observed y-value equals the predicted y-value.
Take, for instance, we have the following data entry:
Observed value = 69.4
Predicted value = 70.4
The residual (r) would be:
Residual value = 69.4 - 70.4 = -1
Therefore the residual value will be -1

Answer is B. No matter what the x or y will be the result will be 0. Anything multiplied by 0 is equal to 0.
Just multiply my friend. The answer is 196
