Hey there, in order to find out what graph corresponds to the equation, you have to convert it to slope-intercept form. y=mx+b

OpenStudy (steve816):

Do you think you can do that?

OpenStudy (yeval76):

I tried but I couldn't figure it out...

OpenStudy (steve816):

Add x to both sides, then divide the equation by -2 to get it to be just y

OpenStudy (yeval76):

y = -3 + x/-2

OpenStudy (yeval76):

@steve816

OpenStudy (steve816):

Yes, so the equation would be \[y=-\frac{ 1 }{ 2 }-3\]

OpenStudy (steve816):

First things first, our slope is negative, so the line will be going down from left to right.

OpenStudy (yeval76):

Would the answer be D

OpenStudy (steve816):

Not quite, remember, the y-intercept is -3. That is when the line crosses the y axis.

OpenStudy (yeval76):

I meant B sorry...

OpenStudy (yeval76):

Because it crosses the y-int at -3 and it goes descneding from left to right

OpenStudy (yeval76):

@steve816

OpenStudy (steve816):

Yes that is the answer! Great, you did it :)

OpenStudy (yeval76):

Thank You!!
