SHMOOP… there it is…
- 00:05
The graph of the line y equals 1/12x minus 12 is parallel to line I.
- 00:11
Which one of the following could be an equation for line I?
- 00:15
And here are the potential answers…
- 00:22
So… what is this question asking?

Do we really know the innards of y equals mx plus b?
- 00:27
Well this equation is already written in y equals mx plus b form and we know that parallel
- 00:32
lines all have the same slope.
- 00:34
The slope in this case is circled here – it’s one twelfth.
- 00:38
So we just have to look for a line that has 1/12th in the “m” area…
- 00:43
Well… B would get us there, but it’s written as NEGATIVE
- 00:46
so our response to that option is… negative as well.
- 00:49
The answer is D.
- 00:50
As in, “Dinner.”
