How to find the slope of a line

Topic:- Slope of a line

Slope is used to describe the steepness, incline, gradient, or grade of a straight line.Similarly a line segment is a part of a line that is bounded by two distinct end points,Lets see how to find the
slope if these end points are given.

Question:-

find the slope passing through 5,5 and -4,5

Answer:-

                
we know that, slope of line  m
=  y2-y1
--------
  x2-x1


here, we have (5,5) so, xl = 5 and yl = 5

similarly   (-4,5) so, x2 = -4 and y2 =5
                         
                                          5-5       0
Now, lets find the slope of the line  m= ------- = -----
                                         -4-5      -9

The slope of line =  0
