Question

lauren is preheating her oven before using it to bake. lauren wants to predict the final temperature after $x$ minutes. she wrote the equation $y = 76 + 20x$, where $y$ represents the final temperature in degrees fahrenheit. what is the meaning of the $y$-value when $x = 1$? answer the ovens temperature after 0 minutes. the change in degrees fahrenheit for every change of one minute. the time when the ovens temperature is $0^{circ}$. the ovens temperature after 1 minute.

Explanation:

Step1: Substitute \(x = 1\) into the equation

Given the equation \(y=76 + 20x\), when \(x = 1\), we have \(y=76+20\times1\).

Step2: Calculate the value of \(y\)

Since \(x\) represents the number of minutes and \(y\) represents the final temperature, when \(x = 1\), \(y\) represents the oven's temperature after 1 minute.

Answer:

The oven's temperature after 1 minute.
