Answer:


y-6=(1)/(3) (x+1)

Explanation:

The point-slope formula is
y -y_(1) =m(x -x_(1)) where we substitute a point (x,y) for
(x_(1),y_(1)).

We have m=
(1)/(3) and (-1, 6). We input m and
x_(1) =-1\\y_(1)=6.


y-6=(1)/(3) (x-(-1))\\y-6=(1)/(3) (x+1).

We can convert into the slop-intercept from by simplifying the parenthesis and solving for y.


y-6=(1)/(3) (x+1)\\y-6=(1)/(3)x +(1)/(3)\\y-6+6=(1)/(3)x +(1)/(3)+6\\\\y=(1)/(3)x +6(1)/(3)\\\\
