Look at Part 1. What type of data is represented by the graph?
What is the approximate location of point A?
Does there appear to be any correlation between the number of floors in an apartment complex and the number of apartments on each floor? How do you know?
Yes; as the number of floors increases, so does the number of apartments.
What type of correlation is this?
Does the data have a linear or non-linear association? Explain your reasoning.
Linear. Possible explanation: the data loosely forms a line.
Look at Part 2. What are the locations of points A and B on the graph?
What is the slope of the line through points A and B?
Is the slope of the line the same for the whole line? What does this say about the graph's rate of change?
Yes; this means the rate of change is constant.
What is the y-intercept of the line?
What is the equation of the line?
