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?

00:24

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.”
