Solving systems by graphing
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will solve systems by graphing through guided practice and application.
In this lesson, we'll explore solving systems by graphing. Mathematical thinking develops logical reasoning and problem-solving abilities.
A coordinate graph (or coordinate plane) lets us show the location of points using two numbers. The horizontal line is the x-axis, and the vertical line is the y-axis. Every point has coordinates (x, y) that tell how far to move right/left and up/down from the center (origin). For example, the point (3, 2) means move 3 units right and 2 units up. Graphs help us visualize patterns and relationships!
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.

Instructions
Materials Needed
- Notebook
- Calculator (if needed)
- Graph paper
Solve for x: x + 7 = 15
Solve for y: 3y = 12
If 2x - 5 = 9, what is x?
Teaching Tip
For advanced learners: Encourage deeper analysis and real-world connections. Consider extension activities that allow students to apply solving systems by graphing to novel situations.
