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.
