Graphing on a Coordinate Plane

This topic covers finding coordinates and quadrants of points on a plane and graphing the equations on a coordinate plane.

Topic: Quadrants and Coordinates

  • A coordinate plane is a plane containing a horizontal number line, the x-axis, and a vertical number line, the y-axis

  • The coordinates of a point are given by an ordered pair. An ordered pair is a pair of numbers that can be used to locate a point on a coordinate plane

  • The intersection of the x-axis and the y-axis is called the origin. The coordinates of the origin are (0, 0)

  • The points to the left of 0 on a coordinate plane are negative and to the right of zero are positive. The points up from zero on a coordinate plane are positive and down from zero are negative

  • Quadrant I has both the coordinates positive and Quadrant III has both the coordinates negative. Quadrant II has x-coordinate negative and y-coordinate positive. Quadrant IV has x-coordinate positive and y-coordinate negative

Topic: Graphing an Equation of a Line

  • A coordinate plane is a plane containing a horizontal number line: the x-axis; and a vertical number line: the y-axis

  • The coordinates of a point are given by an ordered pair. An ordered pair is a pair of numbers that can be used to locate a point on a coordinate plane

  • To plot an equation, find the ordered pairs and plot them on a graph to form a line

Topic: Plotting Points

  • To plot a point (x, y) on a coordinate plane, move x units right/left and y units up/down depending on the signs of the x and y coordinates

  • Area of a square = Side x Side and perimeter = 4 x s
