Graphs are really useful for solving word problems that involve straight lines! Here’s how to use them:

1. Identify Your Variables: First, decide what your variables will be. For example, if you want to know how many items were sold, you can use $x$ to represent the number of items and $y$ for the money made.

2. Create the Equation: Next, turn the word problem into a linear equation. If you know the price of each item, your equation might look like $y = mx + b$. Here, $m$ is the price for each item.

3. Draw the Graph: After you have your equation, it’s time to create the graph! The points where your graph crosses the x-axis and y-axis are very important and give you useful information about the problem.

4. Find Solutions on the Graph: Look for points where the line crosses over or where two lines meet. These spots usually show the solutions to your problem, making it easier to understand what’s going on.

Using graphs not only helps you find the solution but also gives you a better idea of how different factors work together!
