<P> In mathematics , the slope or gradient of a line is a number that describes both the direction and the steepness of the line . Slope is often denoted by the letter m ; there is no clear answer to the question why the letter m is used for slope , but it might be from the `` m for multiple '' in the equation of a straight line `` y = mx + b '' or `` y = mx + c '' . </P>
