5
$200

6
Find the equation of a line, in slope-intercept form, that passes through the points (0, -7) and (3, 2) Slippery Slopes- $300

7
$300

8

12
To solve a proportion, you use the ______ _______ property. Proportion Control $100

13
cross product $100

14
Solve the proportion:. Proportion Control- $200

15
x = 4 $200

16
Solve the proportion. Proportion Control- $300

17
$300

18
If y varies directly as x, and the constant of variation is ½, find x when y is 12. Proportion Control- $400

19
x = 24 $400

20
If x and y vary directly, what do you know about b in the equation y = mx + b ? Proportion Control- $500

21
b = 0 $500

22
Draw an example of a scatter plot with a strong positive correlation. Include at least 8 points on your plot. This Plot Is Scattered! - $100

23
Sample Answer: $100

24
In a certain scatter plot, the correlation coefficient is found to be -0.75. Describe how close the data points are to the least squares line and what type of correlation is shown. This Plot Is Scattered! - $200

25
Most of the data is relatively close to the line and the line represents a negative correlation. $200

26
Find the equation of a least squares line (to 3 decimal places) in y = ax + b format for a line with the following data: This Plot Is Scattered! - $300 x01234 y2.13.84.65.05.36.2

27
$300

28
This Plot Is Scattered! - $400 Find the correlation coefficient (to 2 decimal places) for the following set of data: x-84.212-5.379.17 y5.223.14.86.42-2

29
r = -0.15 $400

30
Why will the calculator always fit a least squares line even to data that has no reliable correlation? This Plot Is Scattered! - $500

31
The calculator computes the line using a formula. The correlation coefficient tells you how useful that line may or may not be. $500

32

You’re standing on a cliff flying a kite when your kite falls into the lake below. The angle of declination from your line of sight to the kite is 30 degrees. The string of the kite, which is fully extended, is 400 feet. What is the height of the cliff? Gettin' Triggy With It - $500

51
The cliff is 200 feet above the lake. $500
