In Algebra, we often use the rectangular coordinate system to
graph lines, parabolas and other formulas. Important terms to be
familiar with include the y-axis, the x-axis, y-coordinates,
x-coordinates and points.The rectangular coordinate system can
also be called the coordinate system or the x-y axis. The
rectangular coordinate system is a general way that we graph a
lot of information. You hear it call called the rectangular
coordinate system; you'll hear it called the coordinate system
sometimes you call the xy axis. There's different ways of
phrasing it all of which are always going to be referring to
this sort standard grid that you probably seen before, so the
few things that we need to talk about this are there's an x axis
and a y axis. The x axis is the one on a horizontal the y axis
is the one that goes up and down. Okay how we refer to specific
points is, is an x coordinate and a y coordinate okay? So if I
say the point 3, -2 what that means is we go down the x axis 3
so positive is in the right di
