8.18 Points on a Grid

Coordinate plane
  • Coordinate plane has two axes. They intersect at right angle and form four quadrants.
  • The two number lines form the axes.
  • The horizontal number line is called the x-axis.
  • The vertical number line is called the y-axis.
  • The center of the coordinate plane is called the origin. It has the coordinates of (0,0).
  • Locations of points on the plane can be plotted when one coordinate from each of the axes are used. This set of x and y values are called ordered pairs.
  • The points in a grid are named by ordered pairs.
  • The first number gives the position to the right of 0.
  • The second number gives the position above 0.
  • The axes along which the ordered pairs are marked are called co-ordinate axes.
Example: What is the ordered pair of point A?

Answer: (2,1)


Directions: Answer the following questions. Also take a graph paper and plot at least 15 points and label the ordered pair.
Q 1: A device for locating points in a plane is called ____. It is formed by drawing two number lines at right angles to each other and intersecting at their zero points.
