                  Ex:  Find an equation of the line through (2,3) with slope angle 135°





                  2) Equation Of A Line Which Is Passing Through The Given Two Points:

                  Let line d be passing through the points A(x 1, y 1) and B(x 2, y 2)
                  and let P(x, y) be any point on the line. Then, the slope of the

                  line d is m AB= m AP


                   y 2  y 1  y y  1
                   x   x   x x
                    2   1      1





                  Ex:  Write the equation of the line passing through the points P and Q, if

                  a) P(1,0) and Q(4,2)                                      b) P(-2,-1) and Q(2,3)













                  Ex:  Show that the equation of the line passing through the
                  points A(a, 0) and B(0, b) is
