Question

the graph below shows the relationship between time and the height of a hot air balloon. time (in minutes) which of the following best describes the slope of the graph? a the number of minutes the balloon has been in the air b the distance the balloon is from the ground in feet c the number of minutes the balloon takes to reach its maximum height d the rate at which the balloon rises in feet per minute

Explanation:

The slope of a graph representing height (y - axis) versus time (x - axis) is calculated as $\frac{\text{change in height}}{\text{change in time}}$. In the context of the hot - air balloon, this represents the rate of change of height with respect to time, which is the rate at which the balloon rises in feet per minute.

Answer:

D. the rate at which the balloon rises in feet per minute
