Rearrange the given equation into the form of y=mx+c.
%28k%2B1%29x%2B2y=6
2y=-%28k%2B1%29x%2B6
cross%282%29y%2Fcross%282%29=%28%28-%28k%2B1%29%29%2F2%29x%2B6%2F2
y=highlight%28%28%28-%28k%2B1%29%29%2F2%29%29x%2B3 ... The highlighted part is the slope.
%28-%28k%2B1%29%29%2F2=k-2
%28-k-1%29%2F2=k-2
%28%28-k-1%29%2Fcross%282%29%29cross%282%29=%28k-2%292
-k-1=2k-4
-k-2k=-4%2B1
-3k=-3
k=%28-3%29%2F%28-3%29
k=1
