❖ Which Quadrant or Axis? Points on the Coordinate Plane (\(2D\)), A beginner-friendly lesson to decide whether a point lies in a quadrant (\(Q_1–Q_4\)) or on the \(x\)– or \(y\)-axis, with \(10\) examples.

📚 Topics Covered:

– Quick refresher: axes & origin \((0,0)\) on the coordinate plane (\(2D\))

– The four quadrants: \(Q_1 (+,+), Q_2 (−,+), Q_3 (−,−), Q_4 (+,−)\)

– Boundary rule: if \(x=0\) or \(y=0\), the point is on an axis, not in a quadrant

– How the signs of \((x,y)\) determine the quadrant

– Classifying \(10\) example points step by step

✔️ Important Points:

✅ Say in a quadrant, on an axis, at the origin \((0,0)\)

✅ \(Q_1 (+,+), Q_2 (−,+), Q_3 (−,−), Q_4 (+,−)\)

✅ Points with \(x=0\) or \(y=0\) lie on an axis (not in any quadrant)

🎯 Whether you’re a student, teacher, or math enthusiast, this lesson makes identifying whether a point lies in a quadrant or on an axis of the coordinate plane (\(2D\)) simple and easy.
