Answer:
Step-by-step explanation:
<u>Define the given points</u>:
Use the <u>slope formula</u> to determine the slope of the line:
Use the <u>point-slope formula</u> to determine the equation of the line.
Substitute the found slope and point (4, -2):
Multiply both sides by 5:
Expand the brackets:
Add 3x to both sides:
Subtract 10 from both sides:
Answer:
24.5
Step-by-step explanation:
A calculator or spreadsheet is good for doing this sort of computation.
_____
You add up the magnitudes of the differences between the given y-value and the corresponding value you get from the equation. For the first couple of points, these values are ...
... |3 - (0.1·1 +2.9)| = 0
... |2.5 -(0.1·6 +2.9)| = |2.5 -3.5| = 1
The computation proceeds like this for the remaining 6 points, and the numbers added. The result is 24.5.
