Question 2
2.

Solve It! Predict the number of CDs sold and the number of albums downloaded in 2010. Explain your reasoning.

Problem 1 Got It? What type of relationship does the scatter plot you created in the previous item show?
positive correlation
negative correlation
no correlation
Problem 2 Got It? Use the trend line you drew in the previous item to predict the approximate body length of a 7-month-old panda.
About 29.1 in.
About 21.8 in.
About 24.4 in.
About 34.2 in.
Question 9
9.

Problem 3 Got It? Reasoning: What does the slope of the line of best fit in Problem 3 tell you about the rate of change in the cost?

Consider your scatter plot and the data in the previous item. What type of relationship is shown?
Strong positive correlation
Positive correlation
Little to no correlation
Negative correlation
Strong negative correlation
Consider your scatter plot and the data once more. Predict the average maximum daily temperature in January at a latitude of 50° N.
Choose the most reasonable prediction.
About 10°F
About 20°F
About 30°F
About 40°F
Review Lesson 5-6: Write an equation of the line in slope-intercept form that passes through the given point and is parallel to the graph of the given equation.
y + 3 = 5(x - 2)
y = -2x + 3
y = 5x - 13
Review Lesson 5-6: Write an equation of the line in slope-intercept form that passes through the given point and is parallel to the graph of the given equation.
y = x + 9
y = -x + 5
y = 5x
