**Important Points of the Coordinate Plane**

- The left and the bottom part of the plane have negative x-axis and negative y-axis for negative integers. The point where the number lines intersect is called the origin.
- A coordinate plane is a tool used for graphing points, lines, and other objects. It functions like a map that follows directions from one point to another.
- The two number lines divide the coordinate plane into 4 regions. These regions are called Quadrants.
- The first quadrant (+, +) known as the positive coordinates quadrant, is represented by the Roman numeral I.
- The second quadrant (-, +) is represented by the Roman numeral II.
- The third quadrant (-, -) is represented by the Roman numeral III.
- The fourth quadrant (+, -) is represented by the Roman numeral IV.
- The coordinates of any point are enclosed in brackets.

**Coordinate Plane Example**

**1.**** ****You are at (−4, 3). Move 5 units right and 2 units up. Write the coordinates of the point where you reach.**

Ø Moving 5 units to the right will reach −4 + 5 = 1 on the x-axis.

Ø Moving 2 units up will reach 3 + 2 = 5 on the y-axis.

Ø So, the coordinates of the point where we reached is (1, 5).
