Welcome to Plotting Points on a Coordinate Plane
When you look at a coordinate plane, you see a grid formed by two perpendicular number lines: the horizontal x‑axis and the vertical y‑axis. These axes intersect at a point called the origin (0, 0). The plane is divided into four quadrants, but today we’ll focus on the **first quadrant**, where both x and y values are positive.
Introduction to the First Quadrant
In the first quadrant, every point has coordinates (x, y) with x > 0 and y > 0. This means the point lies to the right of the y‑axis and above the x‑axis. Understanding this region is essential for graphing real‑world situations such as distance‑time relationships, budgeting scenarios, and scientific measurements where only positive values make sense.
How to Plot a Point in the First Quadrant
- Identify the coordinates. For example, the point (3, 4) tells you to move 3 units right from the origin along the x‑axis.
- Mark the x‑value. On the x‑axis, count three units to the right and place a small tick.
- Mark the y‑value. From that tick, move vertically upward four units.
- Place the point. The intersection of these movements is the plotted point.
