The graph at the left is a scatter plot with 40 points, each representing the temperature of the ocean water, measured at a fixed location off the coast of West Iceland, and the air temperature, measured on land at a fixed location in West Iceland. Both the water temperature and the air temperature, in degrees Celsius, were measured at noon on Wednesday of each of 40 consecutive weeks last year. The solid line is the regression line and the dashed line is the line through the points (0,0) and (6,6).
Use the drop-down menus to fill in the blanks in each of the following statements based on the information given by the graph.
The relationship between the water temperature and the air temperature is

Official Explanation :
The regression line shows the overall correlation between the water temperatures and the air temperatures. The regression line slopes upward, meaning that higher water temperatures tend to be associated with higher air temperatures. This means the relationship between the water temperature and the air temperature is positive.
Both the regression line and the dashed line slope upward, but the dashed line is steeper. This means the slope of the regression line is less than the slope of the dashed line.
The correct answers are "positive" in the first drop-down menu and "less than" in the second drop-down menu.
