A. The Coordinate Plane

xaxis – the horizontal axis

yaxis – the vertical axis

origin – the point where the x and y axis intersect……(0, 0)

quadrants – the four “corners” of the coordinate plane.

positive numbers – numbers to the right of the origin on the xaxis and numbers above the origin on the yaxis.

negative numbers – numbers to the left of the origin on the xaxis and numbers below the origin on the yaxis.
B. Graphing an Ordered Pair like (2, 6), where the xvalue is always the first number and the yvalue is always the second number.
 Move right or left from the origin.
 Right – if the xvalue is positive.
 Left – if the xvalue is negative.
 Move up or down from the xvalue.
 Up – if the yvalue is positive.
 Down – if the yvalue is negative.
 Mark your point after making the two moves.
C. Graphing Horizontal and Vertical Lines
 y = c (c being any #) is a horizontal line through the ordered pair (0, c).
 x = c (c being any #) is a vertical line through the ordered pair (c, 0).
