Coordinate System

Frequently Asked Questions

What is abscissa and ordinate?

The abscissa is the coordinate along the x-axis. The ordinate is the coordinate along the y-axis. A point is written as (x; y).

How many quadrants does a coordinate plane have?

4 quadrants: I (x>0,y>0), II (x<0,y>0), III (x<0,y<0), IV (x>0,y<0).

How do you find the distance between two points?

d = √((x₂−x₁)²+(y₂−y₁)²). For points on the same axis: |x₂−x₁|.
