Question

right after takeoff, a hot air balloon ascends at a constant rate of 400 feet per minute. you just figured out that the slope is 400. what does the slope mean in this situation? the balloon’s elevation increases 400 feet every minute. the balloon’s elevation is at 400 feet.

Explanation:

In a linear relationship between time (x-axis) and elevation (y-axis), the slope represents the rate of change of the dependent variable (elevation) with respect to the independent variable (time). Here, the slope of 400 corresponds to the given constant ascent rate.

Answer:

The balloon's elevation increases 400 feet every minute.
