Question

while being deflated, a hot - air balloon loses 300 cubic meters of air every 3 minutes. after 6 minutes the balloon has 900 cubic meters of air. the volume of the air in cubic meters, y, is a function of the time in minutes, x.
rate of change: - 100
first, substitute the rate of change for m in the equation.
y = \square x + b
\\(y = mx + b\\)
rate of change

Explanation:

Step1: Identify the rate of change

The rate of change (slope \( m \)) is given as -100.

Step2: Substitute \( m \) into the equation

The linear equation is \( y = mx + b \). Substituting \( m = -100 \) into the equation, we get \( y = -100x + b \).

Answer:

-100
