Q. Malik is preheating his oven before using it to bake. Malik wants to predict the final temperature after

x

minutes. He wrote the equation

y=72+30 x

, where

y

represents the final temperature in degrees Fahrenheit. What could the number

30

in Malik's equation represent?

\newline

The change in minutes for every change of one degree Fahrenheit.

\newline

The time when the oven's temperature is

0^{\circ}

.

\newline

The oven's temperature after

1

minute.

\newline

The change in degrees Fahrenheit for every change of one minute.

Understand Equation Representation: Analyze the given equation $y = 72 + 30x$ to understand what each term represents. $\newline$ The equation is in the form of a linear equation $y = mx + b$ , where $m$ is the slope and $b$ is the y-intercept. In the context of this problem, $y$ represents the final temperature in degrees Fahrenheit, and $x$ represents the time in minutes. The number $72$ is the starting temperature of the oven before preheating, and the number $30$ is the rate of change of the temperature with respect to time.
Interpret Number $30$ : Determine what the number $30$ could represent based on the structure of the equation. $\newline$ Since $30$ is multiplied by the time $x$ , it represents the amount by which the temperature increases for each minute. Therefore, the number $30$ represents the change in degrees Fahrenheit for every change of one minute.
