The residual value is the vertical distance between the observed value and the predicted value. In other words,
residual value = point in scatter plot - point in the line of best fit
When , the corresponding scatter plot point is at
and the corresponding point in the line of best fit is
[can be seen from the graph]
Hence,
residual value = . Answer choice B is correct.
ANSWER: B
Answer:
Distance between the points = 10 units
Step-by-step explanation:
Given points:
(0,-2) and (-8,-8)
To find the distance between the two points.
Solution:
Applying distance formula to find the distance between the points.
For points and
the distance is given as:
Plugging in the given points in the formula.
Since distance is always positive. So units.
