Question

slopes dont have to be positive sign out 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. finally, think about this scenario. is the slope positive, zero, or negative? the hot air balloon is at an elevation of 2,200 feet and is descending at a constant rate of 400 feet per minute. the slope is

Explanation:

The slope represents the rate of change of elevation with respect to time. Since the balloon is descending (elevation decreases as time increases), the rate of change is negative.

Answer:

negative
