Question
If the slope is - 
, what does that mean?
Use the given line of best fit to approximate the rate of change relative to the scatter plot above.
- gain 5 hour of sleep for 7 cups of coffee
- lose 5 hours of sleep for 7 cups of coffee
- lose 7 cups of coffee for 5 hours of sleep
- lose 5 cups of coffee for 7 hours of sleep
Hint:
A trend line with a negative slope indicates a negative relationship between the two variables. When one goes up, the other goes down, and vice versa.
The correct answer is: lose 5 hours of sleep for 7 cups of coffee
A trend line with a negative slope indicates a negative relationship between the two variables. When one goes up, the other goes down, and vice versa.
The slope - means loses 5hours of sleep for 7 cups of coffee.
