Introduction to Graphing Mrs. Kuznia Math 8 Day 18

Coordinate plane Two number lines that intersect at right angles. It contains an X Axis and Y Axis.

Axis X-Axis: The horizontal line in the coordinate plane Y-Axis: The Vertical Line in the Coordinate plane.

Origin The middle, or point of intersection, in the coordinate plane. This point is labeled (0,0)

Ordered Pair Identifies the location of a given point. Always in parenthesis (x,y) X- tells you how far to move to the left or right Y-tells you how far to move up or down

Quadrants -Quadrants start in the upper right corner, and go counter clockwise; - Must Be Roman Numerals!!

Graph Graph the following coordinates: (5,4) (-6,3) (-3,-4) (2,-3)

Determine the Coordinates of each point:
