1. ## Slope question

This is simple question but I kept getting -13 when the asnwer should be -7. I can't figure out what I am doing wrong.

5 = 3-k/4+6
5 = 3-k/-2
-10 = 3-k
-13 = k?

hmmm
I probably did it wrong, please correct! thanks so much!

I'm trying to interpret the problem. I'm going to assume that it is $5=\frac{3-k}{4}+6$

First, subtract 6 from both sides to get $-1=\frac{3-k}{4}$

Now multiply both sides by 4 to get $-4=3-k$.

Solving for $k$, we see that $-7=-k\implies k=7$.

If the answer really is $k=-7$, then I think the problem would have to be $5=\frac{3+k}{4}+6$

Does this make sense? If you have further comments or questions, please post back!

3. I figure it out, I messed up the fomula. haha
The orginal fomula was M = y2-y1/x2-x1.

Thanks anyways though! This forum is so awesome when it comes to homework help
