y-axis The VERTICAL AXIS(vertical NUMBER LINE) in a CARTESIAN
COORDINATE SYSTEMgraph. POSITIVE NUMBERs are up from the
ORIGINon the y-axis, and NEGATIVE NUMBERs are down from the
origin on the y-axis.y-interceptThe point on a GRAPHin which a LINE SEGMENTintersects the
y-axis, which is when x= 0.
z-axis The axis in a three-dimensional coordinate system that is
PERPENDICULARto the xy-plane.
z-coordinateThe coordinate that corresponds to the z-axis in a three-
dimensional coordinate system, listed as the third coordinate in an
ordered triple as (x, y, z).
zero The mathematical symbol used to show no measurable VALUE.
