Graphing Linear Equations Using Intercepts
By Se K.
A worked-example practice set for 9th graders that teaches how to graph equations in standard form by finding the x- and y-intercepts. It builds skills in substitution, solving linear equations, and plotting points, with key vocabulary defined up front and a fully worked example to model each step.
Customize for your classroom
Teacher Guide & Tips
- Use this as a 45-minute guided lesson: model the worked example on the board, then release students to try the practice problems in pairs before a short whole-class check.
- Discussion question: Why does setting y = 0 give you a point on the x-axis, and why is one point not enough to draw a line?
- Scaffold for struggling readers: have them write out the substitution step (e.g., 2x + 3(0) = 6) before solving, and review the meaning of intercept in plain language.
- Extension for advanced students: ask them to convert an equation from slope-intercept form to standard form and predict the intercepts before graphing.
- Estimated time: about 25 minutes for the worked example and guided practice, plus 15 minutes for independent problems.
