Q. When Quinn got home, he turned the air conditioner on.

\newline

T

represents the temperature in Quinn's home (in degrees Celsius) after

t

minutes.

\newline

T=42-0.7 t

\newline

How fast did the temperature drop?

\newline

degrees Celsius per minute

Given Equation: We are given the equation $T = 42 - 0.7t$ , where $T$ represents the temperature in degrees Celsius and $t$ represents time in minutes. To find out how fast the temperature dropped, we need to look at the coefficient of $t$ in the equation.
Coefficient Analysis: The coefficient of $t$ is $-0.7$ , which means that for every minute that passes, the temperature drops by $0.7$ degrees Celsius.
Rate of Temperature Drop: Therefore, the rate at which the temperature drops is $0.7$ degrees Celsius per minute.
