Find the Rate of Change: Analyzing y=x-4 Linear Function

Given the linear function:

$y=x-4$

What is the rate of change of the function?

The problem asks to find the rate of change of the linear function $y = x - 4$. This function is in the form of $y = mx + b$, where:

• $m$ is the slope, representing the rate of change of the function.
• $b$ is the y-intercept, but it is not relevant for finding the rate of change.

For the function $y = x - 4$, we can compare it with the standard form $y = mx + b$ to identify:

$m = 1$.

Therefore, the rate of change of the function is determined by the coefficient of $x$, which is 1.

Hence, the rate of change of the function is $m = 1$.

The correct answer is: $m = 1$.
