Question 24948: what are the number lines used in a coordinate graph called?
Answer by Earlsdon(6294)   (Show Source):
You can put this solution on YOUR website! The vertical number line is called the y-axis.
The horizontal number line is called the x-axis.
The axes intersect at their zero points called the origin.
The plane containing the x- and y-axes is called the coordinate plane.
Points in the coordinate plane are named by ordered pairs in the form (x, y).
The first number, or x-coordinate (also called the abscissa), corresponds to the number on the x-axis.
The second number, or y-coordinate (also called the ordinate) , corresponds to the number on the y-axis.
