If you know the equation of a proportional relationship, how can you draw the graph of the equation?

If you know the function, you can graph it like this:
So, let's say the x values are 0, 1, and 2.
Lets say the function is y=x+1
So, your outputs would be 1, 2, and 3.
Once you're finished with that, you can create the ordered pairs like so:
(0,1), (1,2), (2,3)
Those would be the ordered pairs.
Hope this helps! :)
