Interpret the slope of the equation you just selected above.
You can use this template to help you if needed:
As the ________ (x-axis) increases by 1, the __________ (y-axis) increases/decreases by ______ (slope).
Question 8
8.
Use the given linear model y= 1.5x + 108 to predict what the noise level would be if 60 people attended.
Question 9
9.
Explain the meaning of the slope of the line in context.
Question 10
10.
Describe the correlation between the variables as either strong or weak and as either positive or negative. Explain your reasoning.
Select all TRUE statements based off the image above.
The y-intercept (from the line of best fit) indicates that a reaction time would be 0 for a person who is about 43 years old.
Reaction time tends to decrease as the age increases.
The correlation looks close to -1, so there is no association between age and reaction time.
The line of best fit indicates that, in general, the reaction time for a 21-year-old should be, on average, about 9.25 milliseconds less than the reaction time for a 20-year-old.
The data in the graph above suggest a linear association. Which of the functions best represents the equation of the line of best fit?
