Coordinate Plane, Functions, and Slope Checkpoint
A free Pre-Algebra lesson from the “Coordinate Plane, Functions, and Slope” unit, with a worked example and practice problems including step-by-step solutions.
This checkpoint mixes the coordinate plane, functions, and slope skills from the unit. It is intentionally cumulative: students identify the topic, choose a method, solve, and check that the answer makes sense before moving on. In Coordinate Plane, Functions, and Slope, the goal is not just to get an answer but to recognize the structure of the problem, choose a reliable strategy, and explain why the result is reasonable. The practice set now includes targeted skill work, transfer questions, and mixed review so students build fluency and retention.
What you'll learn
- Review the major skills from Coordinate Plane, Functions, and Slope
- Choose methods without topic labels
- Explain and check work across a mixed set
Worked example
Problem. What quadrant contains the point (-3, 5)?
- The x-coordinate is negative, so move left.
- The y-coordinate is positive, so move up.
- Left and up is Quadrant II.
- Connect the calculation back to Coordinate Plane Foundations so the method, not just the arithmetic, is clear.
Answer: Quadrant II
