Question 68883: Given the points (1,-3) and (-2,-3) on a line, what would the slope be?

Slope is given by the formula:

      Rise     Change in y       y2 - y1      
m =  _____  =  ___________   =   ________
    
      Run      Change in x       x2 - x1  
     

Let ( 1, -3) = (x1, y1)
    (-2, -3) = (x2, y2)

Substitute the values to the formula of the slope

     -3 - (-3)       0
m = __________   =  ___  =  0 ; The graph is a horizontal line

     -2 -  1        -3
