# What variable is on the horizontal axis, degrees north latitude or average annual snowfall?

On the vertical axis? • Mouseover a point to see the coordinates of that point. What are the coordinates of the point you are looking at? Which city’s data are you examining? What does the x-coordinate represent? The y-coordinate? • Which city’s point is closest to the upper right corner of the graph? Which city’s point is closest to the lower left corner? Give the coordinates of both points. Why do you think these cities are the most extreme values in this scatter plot? Mention degrees latitude and snowfall in your explanation. • Notice that the overall shape of this scatter plot resembles a line. A line that data well is called a trend line. Would the trend line for this scatter plot have a slope that is positive, negative, or near zero? Click on Show least squares fit line to check your answer. (The least squares fit line is a type of trend line.) • You should see that the trend line for this scatter plot has a positive slope. What does this suggest about cities further north and av
