Quadrants

The four quadrants, and the coordinates they contain

Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.

This lesson is on Standard Position, Radian Measure, Incorporating the Axes & Other Quadrants with examples and a detailed explanation of the topic.

In this lesson we will use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate).

A quadrant is one of each of the four sections of the coordinate plane.
