True or False:
A good line of best fit must follow the slope or pattern of the points.
True
False
True or False:
The line of best fit must go through the origin.
True
False
True or False:
A line of best fit should have approximately the same number of points above and below the line.
True
False
True or False:
The line of best fit must go through at least 5 points.
True
False
Is the line of best fit drawn correctly?
Yes, the line is drawn in the correct place.
Yes, the line separates the data points in half.
No, the line cuts the data in half but does not follow the slope of the points.
No, the line does not go through the origin.
Which of the following lines represent the line of best fit for the scatter plot?
A
B
C
D
Which of the following lines represent the line of best fit?
A
B
C
None - there is no line of best fit
Is the line of best fit drawn correctly?
Yes, it cuts the data points in half
Yes, it follows the slope of the points
No, it doesn't follow the slope of the points
No, it doesn't split the points in half
Use the line of best fit to estimate the y value when x=4
y=8
y=5
y=3
y=1
Is the line of best fit drawn in the correct place?
No, the line does not dollow the slope of the points
No, the line does not go through the origin
Yes, the line of best fit is drawn in the correct place
No, the line does not approximately split the points in half
Use the line of best fit to estimate the x value when y=9
x=3
x=9
x=5
x=6
Find the slope between the points (6,4) and (9,9) on the line of best fit.
Remember the slope formula: y2-y1 / x2-x1
-1.25
1.25
0.8
-0.8
Which of the following lines represent the line of best fit?
A
B
C
There is no line of best fit because there is no association.
Find the slope between the points (2,14) and (6,2) on the best fit line.
-3
3
-1/3
1/3
Use the slope found in question 14 and one point to find the y intercept of the line of best fit.
Points (2,14) and (6,2) AND slope -3
Remember y=mx+b
10
40
30
20
Using the slope and y intercept write the final slope intercept equation for the line of best fit.
Remember y=mx+b
slope: -3 and y int.: 20
y= 3x +20
y= 3x -20
y = -3x +20
y= -3x -20
Using the equation of the best fit line found in problem 16, estimate the y value when x = 14
y = -3x +20
y= -36
y= -14
y= -22
y= 22
