# Plotting points and naming quadrants

On a coordinate diagram the horizontal line is called the x-axis and the vertical line is called the y-axis. The point where the x-axis and y-axis meet is called the origin, O. The coordinates of a point are written (a,b) where a is the distance across (left or right) and b is the distance up or down from the point (0,0). The coordinate grid is divided into four sections called quadrants: Graph (3,4) and tell wich quadrant is it in. The point (3,4) is in Quadrant I
