Slope
A quantity which gives the inclination of a curve or line with respect to another curve or line. For a Line in thePlane making an Angle 
with the x-Axis, the Slope 
is a constant given by
where
and 
are changes in the two coordinates over some distance. It is meaningless to talk aboutthe slope in 3-D unless the slope with respect to what is specified.- Total Space
