The function you've provided is:

$f(x) = -\frac{4}{3}x + 15$

This is a linear function, which follows the standard form of a linear equation $f(x) = mx + b$, where:

• $m = -\frac{4}{3}$ is the slope of the line.
• $b = 15$ is the y-intercept, which means the line crosses the y-axis at $(0, 15)$.

Would you like a detailed explanation on how to analyze or graph this function?

Here are 5 related questions to consider:

1. What is the slope of the line and how does it affect the graph?
2. How would you find the x-intercept of this function?
3. What is the domain and range of this linear function?
4. How do you graph a linear function like this one?
5. Can you find another point on the line besides the y-intercept?

Tip: When graphing a linear function, the slope tells you how steep the line is and in which direction it tilts.
