Question

the elevation e (in feet) of a hot air balloon and its time t (in minutes) are related by a linear equation. consider the graph of this equation, with time represented on the horizontal axis and elevation on the vertical axis. is the slope positive, zero, or negative? the hot air balloon is at an elevation of 300 feet and is ascending at a constant rate of 900 feet per minute. the slope is

Explanation:

The slope represents the rate of change of elevation with respect to time. Since the balloon is ascending (elevation increases as time passes), the rate of change is positive.

Answer:

positive
