1. Lukecrayonz

y2-y1/x2-x1

2. Lukecrayonz

1-4/x-1=-3/5

3. Lukecrayonz

-3/x-1=-3/5

4. Cherishyou

that may be correct lls

5. CLester13

The answer choices are: A. 6 B. 7 C. 8 D. 9 E. 10

6. CLester13

the answer i got is 6.666667 so would it be A or B?

7. Misthorn

Luke took you most of the way -- you don't even really need to do anything from here - you should be able to tell by looking at it: $\frac{ -3 }{ x-1 }=\frac{ -3 }{5 }$

8. CLester13

so you cross multiple

9. Misthorn

You could -- but if you look, you'll see both numerators are the same, so you just need to set the denominators equal to each other. (x-1 = 5)

10. Misthorn

Sure. Actually, I started out suggesting you cross-multiply, but when I was making the fraction in the equation editor, I noticed that I could solve it just by looking at it instead.

ok. well thanks a lot
