Question

When graphing a proportional relationship represented by y=mx, which point is not on the graph? (0,0), (0,m), (1,m), (2,2m).

Answer 1

The point is not on the graph is :    ( 0 , m)

The proportional relationship represented by  : y=mx  

 The point is not on the graph is that point that does not meet equality as follows :

 y = m*x

  ( 0,0 )         0 = m * 0    0 = 0    

 ( 0 , m)      m = m*0     m = 0   The point is not on the graph

  (  1 , m )       m = m * 1     m = m

  ( 2 , 2m )     2m = m * 2    2m = 2m
