The graph below shows the relationship between the number of years after a car is purchased and the car’s value. Which statement correctly describes the relationship shown in the graph?

The car’s initial value is $30,000, and the car’s value decreases $2,000 each year.

The car’s initial value is $2,000, and the car’s value increases $30,000 each year.

The car’s initial value is $18,000, and the car’s value increases $2,000 each year.

The car’s initial value is $30,000, and the car’s value decreases $12,000 each year.

Part A: Use the graph to find the slope. What does it represent in this situation?

4 cubic yards of topsoil per dollar

8 cubic yards of topsoil per dollar

The graph shows the altitude above sea level of a weather balloon over time. The trend line passes through the points (0, 453) and (10, 359). Which statements about the graph are true?

In general, the balloon is losing altitude.

The weather balloon started its flight at about 455 feet above sea level.

After 4 minutes, the weather balloon had an altitude of about 415 feet above sea level.

The data show a positive correlation.
