OpenStudy (malcolmmcswain):

A B C and D aren't showing up for me. Can you try posting it again.

OpenStudy (malcolmmcswain):

Also, for the picture try downloading it and then attaching it to your reply.

OpenStudy (anonymous):

first one is a the next one is b then c then d

OpenStudy (malcolmmcswain):

Ok. Great! Let's do this.

OpenStudy (anonymous):

lol im ready!

OpenStudy (malcolmmcswain):

So our equation is in the form y=mx. Do you know what that means?

OpenStudy (anonymous):

yes y-coordinates=m or the slope times x-coordinates right?

OpenStudy (malcolmmcswain):

Good job! That's exactly right. So, all we have to do is figure out the which is the right slope.

OpenStudy (malcolmmcswain):

The first thing we can notice about the slope is it's negative, which means it's going down.

OpenStudy (anonymous):

this one is a bit easyer that the other questions so im going to try to take a guess and them ill ask you if im right aand then you can explain!

OpenStudy (malcolmmcswain):

Negative slopes generally look like this: |dw:1445638370005:dw|
