What is the slope of the line (6, 9) and (-2, -3)?
I think it's -3/4 but I'm not sure. Help please?

Question

anonymous · Answer

Hmm, well crap then I got a lot of questions wrong if that's the right way!

hero · Answer

There's more than one way to solve math problems.

anonymous · Answer

y-9=m(x-6)
y=mx-6m+9

-3=m(-2)-6m+9
-3=-8m+9
-8m=-12
m=3/2

hmmm we all got different answers lol

hero · Answer

y = mx + b
  9 = 6m + b
-3 = -2m + b

9 - 6m = b
2m - 3 = b

b = b

9 - 6m = 2m - 3
9 + 3 = 2m + 6m
12 = 8m
12/8 = m
3/2 = m

anonymous · Answer

What I did was the whole m = y2 - y1 / x2 - x1

hero · Answer

$$m = \frac{9 -(-3)}{6 -(-2)}=\frac{9 + 3}{6 + 2} = \frac{12}{8} = \frac{3}{2}$$

hero · Answer

So there. Now you have have three ways to solve it.

Hey check out this website it actually gives you the answer if you type in the points... thats how i got through geometry. :) http://www.webmath.com just click plots and geometry and fimnd whta you want under The equation of the line

@Anders96  Haha I use that site sometimes :P N @Hero oohh! Yeah I was thinking that the negatives turn into positives, but I wasn't sure. Thanks guys!
