As the elevation increases, the temperature tends to increase.
As the elevation increases, the temperature tends to decrease.
As the elevation decreases, the temperature tends to decrease.
There is no association between the elevation and the temperature.
Explanation
Correct answer: B.
Choice B is correct. The association between the elevation and the temperature of locations in the Lake Tahoe Basin can be described by looking at the direction of the line of best fit. The line of best fit slopes downward, which corresponds to the temperature decreasing as the elevation increases.
Desmos solution:
Note: The line of best fit has a negative slope, so as elevation increases, temperature decreases.

Why the other choices are wrong
Choice A
Choice A is incorrect. This choice would be represented by a line of best fit that slopes from the lower left to the upper right of the graph, which isn't what's shown on the graph.
Choice C
Choice C is incorrect. This choice would be represented by a line of best fit that slopes from the lower left to the upper right of the graph, which isn't what's shown on the graph.
Choice D
Choice D is incorrect. This choice would be represented by a line of best fit that is horizontal or has a slope very close to . This is not what's shown on the graph.
