Question 656329
<pre>
"Abscissa" is another name for "x-coordinate"
"Ordinate" is another name for "y-coordinate".

Look at this graph of the point (3,2)

{{{drawing(400,400,-5,5,-5,5, graph(400,400,-5,5,-5,5),
circle(3,2,.1),circle(3,2,.05),locate(3.2,2.2,"(3,2)") )}}}

The 3 is called the abscissa, and the 2 is called the ordinate.

In this picture the red line, which is 3 units long,
 is the abscissa and the green line, which is 2 units
long, is the ordinate:
{{{drawing(400,400,-5,5,-5,5, graph(400,400,-5,5,-5,5),
circle(3,2,.1),circle(3,2,.05),locate(3.2,2.2,"(3,2)"),
green(line(3,0,3,2)), red(line(0,2,3,2))

 )}}}



Together the abscissa, 3, and the ordinate, 2, make up 
the two coordinates of the point (3,2)
