❖ Learn plotting Points on the coordinate plane (2D) in this beginner-friendly coordinate geometry lesson!

In this video, we explain what the coordinate plane is (also called the Cartesian plane or xy-plane ), how to use the x- and y-axes, which meet at the origin (0, 0), and why plotting a point in two dimensions (2D) requires two values: (x, y).

We’ll plot integers, fractions, and decimals, and use a simple video-game arrows idea:
←/→ for x
↑/↓ for y

📚 Topics Covered:
– What is the coordinate plane (also called the Cartesian plane or the xy-plane)?
(A plane is a flat surface like a sheet of paper or a whiteboard.)
– Axes & origin: horizontal x, vertical y, meeting at the origin (0,0)
– From 1D to 2D: two number lines at right angles
– Ordered pairs (x,y) and what the comma separates
– Quadrants (Q1–Q4) and boundaries (points on axes aren’t in any quadrant)
– How signs control direction: x right/left, y up/down
– Visualizing (x,y) as intersection of x=constant and y=constant
– Step-by-step plotting + practice examples

✔️ Important points:
✅ In 2D, you need two values to locate a point: (x,y)
✅ x＞0 → right; x＜0 → left; y＞0 → up; y＜0 → down
✅ Points on the x-axis or y-axis are not in any quadrant
✅ Q1 (+,+), Q2 (−,+), Q3 (−,−), Q4 (+,−)
