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

4. steve816

Do you think you can do that?

5. yeval76

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

6. steve816

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

7. yeval76

y = -3 + x/-2

@steve816

9. steve816

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

10. steve816

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

12. steve816

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

13. yeval76

I meant B sorry...

14. yeval76

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

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

17. yeval76

Thank You!!
