Aslope is the angle of elevation (or depreciation). 
it's simply the  change in height   of the line.


a function is some formula which relates input (x) and output (y). 

The  slope   of a linear  function . the steepness of a hill is called a  slope . the same goes for the steepness of a line. the  slope   is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
if you need more info i suggest using websites like mathplanet or do a google search about them.
