Question

fwam is preheating his oven before using it to bake. fwam wants to predict the final temperature after $x$ minutes. he wrote the equation $y = 40x + 79$, where $y$ represents the final temperature in degrees fahrenheit. what is the meaning of the $y$-value when $x = 1$?
answer
the change in minutes for every change of one degree fahrenheit.
the time when the ovens temperature is $0^{circ}$.
the rate of change in the ovens temperature over time.
the ovens temperature after 1 minute.

Explanation:

In the equation $y = 40x+79$, when $x = 1$, $y$ gives the temperature at $x = 1$ minute.

Answer:

The oven's temperature after 1 minute.
