How can we write5 situations from the daily life where you can form a linear equation in two variables by graphing method?

Answer 1

1. Budgeting Expenses: If you have a fixed budget for groceries and entertainment, you can represent the amount spent on each as variables and graph their relationship to find combinations that fit your budget.

2. Distance and Time: When traveling, the relationship between distance and time can be modeled as a linear equation, where one variable represents time and the other represents distance, allowing you to graph different speeds.

3. Plant Growth: If you measure the height of a plant over time, you can create a linear equation where time is one variable and height is another, graphing the growth trend.

4. Sales and Commission: If you earn a commission based on the number of items sold, you can graph the relationship between total sales and commission earned to visualize potential earnings based on different sales levels.

5. Cooking Recipe Adjustments: When adjusting a recipe, the number of servings can be one variable and the amount of an ingredient another, allowing you to graph how ingredient quantities change with different serving sizes.
