(I haven't got the Grange graph thing)
When m is 0, the other 2 variables is 0 as well.
when m is 1, the other 2 variable is 20.
when m is 2, the other 2 variable is 40.
when m is 3, the other 2 variable is 60
when m is 4, the other 2 variable is 80.
Im not too sure what you write for the second column in the table, but I think you can just write 20 times the number, whatever m is.
