Any ideas?

anonymous · Answer

First, turn your equations into standard-form: y=mx+b

anonymous · Answer

Then, look at your graph and find the y-intercept and slope.

anonymous · Answer

y = mx+b

anonymous · Answer

Your y-intercept is -3.  So you can throw out equations C and D.

anonymous · Answer

You can also throw out equation B, because you aren't dividing 6 by -2.  The answer is A.

anonymous · Answer

I hope you can see the procedure here and do this in the future.
