Points     1( 0,-4)  2(5,0)
 
 Rise:  Y2 - Y1 =( 0 - ( -4) )= 4
 
Run  :  X2 - X1  ( 5 - 0 ) = 5
 
 m = Rise/ Run= 4/ 5       / Slope
 
   ( 0 ,-4 )    Y- intercept.
 
   Equation of the line :   Y = 4/5 X - 4

2 points  ( 1, 2 ) with coordinates of ( X1 , Y1) = ( 0,- 4)     ( X2 , Y2 ) = ( 5,0)
 
    Then m = (Y2 - Y1 ) / ( X2 - X1) = ( 0- (-4)) / (5- 0 ) = 4/5        l
                                                                                                 l
     You can see on graph  that from ( 0, -4)  to (5,0)                      l             (5,0)    
                                                                                                 l
                                                                                                 l(0.-4
           You see that come up 4 units up ( rise),
            5 unit to the right ( Run)                                                                                      l
