Question

charlotte is preheating her oven before using it to bake. charlotte wants to predict the final temperature after x minutes. she wrote the equation y = 78 + 20x, 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 ovens temperature after 1 minute. the change in degrees fahrenheit for every change of one minute. the time when the ovens temperature is 0.

Explanation:

The equation $y = 78+20x$ models the oven's temperature $y$ (in Fahrenheit) after $x$ minutes. When $x = 1$, we substitute $x = 1$ into the equation to find the temperature at the 1 - minute mark. So the $y$-value represents the oven's temperature after 1 minute.

Answer:

The oven's temperature after 1 minute.
