=====================================================

Introduction

Graphing equations is an essential skill in mathematics, particularly in algebra and calculus. It allows us to visualize the relationship between variables and understand the behavior of functions. In this article, we will use a graphing tool to graph the equation $y - 3 = \frac{1}{3}(x - 5)$ and explore its properties.

Understanding the Equation

The given equation is a linear equation in the slope-intercept form, $y = mx + b$ , where $m$ is the slope and $b$ is the y-intercept. In this case, the equation can be rewritten as $y = \frac{1}{3}x - \frac{5}{3} + 3$ . By comparing this with the slope-intercept form, we can see that the slope is $\frac{1}{3}$ and the y-intercept is $3$ .

Graphing the Equation

To graph the equation, we can use a graphing tool such as a graphing calculator or a computer software like Desmos. We will use the equation $y - 3 = \frac{1}{3}(x - 5)$ to graph the line.

Step 1: Set up the graphing tool

Open the graphing tool and set the window to the appropriate size. For this equation, we can set the x-axis from $-10$ to $10$ and the y-axis from $-10$ to $10$ .

Step 2: Enter the equation

Enter the equation $y - 3 = \frac{1}{3}(x - 5)$ into the graphing tool. Make sure to use the correct syntax and formatting.

Step 3: Graph the equation

Click the "Graph" button to graph the equation. The graph will appear on the screen, showing the line that represents the equation.

Analyzing the Graph

The graph of the equation $y - 3 = \frac{1}{3}(x - 5)$ is a straight line with a slope of $\frac{1}{3}$ and a y-intercept of $3$ . The line passes through the point $(5, 3)$ , which is the solution to the equation.

Key Features of the Graph

Q&A

Q: What is the purpose of graphing equations?

A: Graphing equations allows us to visualize the relationship between variables and understand the behavior of functions. It is a powerful tool for solving problems and making informed decisions in fields such as physics, engineering, and economics.

Q: What are the key features of a graph?

A: The key features of a graph include the slope, y-intercept, and x-intercept. The slope represents the rate of change of the function, while the y-intercept represents the point where the function crosses the y-axis. The x-intercept represents the point where the function crosses the x-axis.

Q: How do I determine the slope of a graph?

A: To determine the slope of a graph, you can use the following formula: slope = (change in y) / (change in x). Alternatively, you can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.

Q: What is the difference between a linear and non-linear graph?

A: A linear graph is a graph that can be represented by a linear equation, such as y = mx + b. A non-linear graph is a graph that cannot be represented by a linear equation, such as a quadratic or cubic equation.

Q: How do I graph a non-linear equation?
