Put the line in slope intercept form, y=mx%2Bb%7D%7D%0D%0A%7B%7B%7B%28k%2B1%29x%2B2y=6
2y=-%28k%2B1%29x%2B6
y=-%28%28k%2B1%29%2F2%29x%2B6

The slope m is,
m=-%28%28k%2B1%29%2F2%29
.
.

I think you want to solve for m=-1 and m=3.
-1=-%28%28k%2B1%29%2F2%29
k%2B1=2
highlight%28k=1%29

3=-%28%28k%2B1%29%2F2%29
k%2B1=-6
highlight%28k=-7%29
