Introduction
In mathematics, the steepness of a graph is often determined by the slope of the line. The slope of a line is a measure of how much the line rises (or falls) vertically over a given horizontal distance. In this article, we will analyze the steepness of the graph of a linear function and determine which function will have the steepest graph.
What is a Linear Function?
A linear function is a function that can be written in the form , where is the slope of the line and is the y-intercept. The slope of a line is a measure of how much the line rises (or falls) vertically over a given horizontal distance.
Slope of a Line
The slope of a line is calculated by dividing the change in the y-coordinate by the change in the x-coordinate. Mathematically, this can be represented as:
Where is the slope of the line, is the change in the y-coordinate, and is the change in the x-coordinate.
Analyzing the Steepness of the Graph
To determine which function will have the steepest graph, we need to analyze the slope of each function. The steeper the slope, the steeper the graph.
Option A:
The slope of this function is . This means that for every unit increase in the x-coordinate, the y-coordinate decreases by 2 units.
Option B:
The slope of this function is . This means that for every unit increase in the x-coordinate, the y-coordinate decreases by unit.
Option C:
The slope of this function is . This means that for every unit increase in the x-coordinate, the y-coordinate increases by units.
Option D:
The slope of this function is . This means that for every unit increase in the x-coordinate, the y-coordinate increases by units.
Conclusion
Based on the analysis of the slope of each function, we can conclude that the function with the steepest graph is Option D: . This is because the slope of this function is the largest, indicating that the graph will rise (or fall) the most vertically over a given horizontal distance.
Why is the Slope Important?
The slope of a line is an important concept in mathematics because it determines the steepness of the graph. A steeper slope indicates a more rapid change in the y-coordinate for a given change in the x-coordinate. This is important in many real-world applications, such as finance, economics, and engineering.
Real-World Applications
The concept of slope is used in many real-world applications, such as:
- Finance: The slope of a stock's price over time can indicate the rate of return on investment.
- Economics: The slope of a country's GDP over time can indicate the rate of economic growth.
- Engineering: The slope of a building's foundation can indicate the stability of the structure.
Conclusion
In conclusion, the steepness of a graph is determined by the slope of the line. The function with the steepest graph is the one with the largest slope. In this article, we analyzed the steepness of the graph of four linear functions and determined that the function with the steepest graph is Option D: . The concept of slope is an important one in mathematics and has many real-world applications.

Frequently Asked Questions
In this article, we will answer some of the most frequently asked questions about analyzing the steepness of the graph of a linear function.
Q: What is the steepness of a graph?
A: The steepness of a graph is a measure of how much the line rises (or falls) vertically over a given horizontal distance. It is determined by the slope of the line.
Q: How is the slope of a line calculated?
A: The slope of a line is calculated by dividing the change in the y-coordinate by the change in the x-coordinate. Mathematically, this can be represented as:
Where is the slope of the line, is the change in the y-coordinate, and is the change in the x-coordinate.
Q: What is the difference between a positive and negative slope?
A: A positive slope indicates that the line rises as the x-coordinate increases. A negative slope indicates that the line falls as the x-coordinate increases.
Q: How does the slope affect the graph?
A: The slope of a line affects the steepness of the graph. A steeper slope indicates a more rapid change in the y-coordinate for a given change in the x-coordinate.
Q: Can you give an example of a linear function with a steep slope?

Q: Can you give an example of a linear function with a shallow slope?
A: Yes, an example of a linear function with a shallow slope is . This function has a slope of 0.1, which is a relatively shallow slope.
Q: How do you determine the steepness of a graph?
A: To determine the steepness of a graph, you need to calculate the slope of the line. You can do this by dividing the change in the y-coordinate by the change in the x-coordinate.
Q: What is the importance of understanding the steepness of a graph?
A: Understanding the steepness of a graph is important because it can help you make predictions about the behavior of a system or a process. For example, if you know that a company's sales are increasing at a rate of 10% per year, you can use this information to make predictions about future sales.
Q: Can you give an example of a real-world application of the steepness of a graph?
A: Yes, an example of a real-world application of the steepness of a graph is finance. In finance, the steepness of a stock's price over time can indicate the rate of return on investment.
Q: How do you graph a linear function?
A: To graph a linear function, you need to plot two points on the coordinate plane and draw a line through them. You can also use a graphing calculator or software to graph a linear function.
Q: What is the difference between a linear function and a non-linear function?
A: A linear function is a function that can be written in the form , where is the slope of the line and is the y-intercept. A non-linear function is a function that cannot be written in this form.
