The secret word this week is ___________________________ and I chose this because it's the name of my pup.
Question 2
2.
True or False:
A good line of best fit must follow the slope or pattern of the points.
Question 3
3.
True or False:
The line of best fit must go through the origin.
Question 4
4.
True or False:
A line of best fit should have approximately the same number of points above and below the line.
Question 5
5.
True or False:
The line of best fit must go through at least 5 points.
Question 6
6.
Is the line of best fit drawn correctly?
Question 7
7.
Which of the following lines represent the line of best fit for the scatter plot?
Question 8
8.
Which of the following lines represent the line of best fit?
Question 9
9.
Is the line of best fit drawn correctly?
Question 10
10.
Use the line of best fit to estimate the y value when x=4
Question 11
11.
Is the line of best fit drawn in the correct place?
Question 12
12.
Use the line of best fit to estimate the x value when y=9
Question 13
13.
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
Question 14
14.
Which of the following lines represent the line of best fit?
Question 15
15.
Find the slope between the points (2,14) and (6,2) on the best fit line.
Question 16
16.
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
Question 17
17.
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
Question 18
18.
Using the equation of the best fit line found in problem 16, estimate the y value when x = 14
y = -3x +20
Question 19
19.

Question 20
20.
Which line represents the line of best fit for the scatterplot?
Question 21
21.
Which line represents the line of best fit for the scatter plot?
Question 22
22.
The graph represents the the amount of money spent in the amount of hours that passed for a babysitter. If the babysitter received $200, about how many hours did the babysitter work?
