y=-1/3-4
Explanation:
point slope form!
y-y=m(x-x)
with the point (-6,-2) and the slope (-1/3) replace the 2nd variables of each variable and replace m with the slope
y-(-2)=-1/3(x-(-6))
then solve that normally
y-(-2)=-1/3(x-(-6))
y+2=-1/3x -2
y=-1/3x-4
I didnt use officially math symbols but i hope you can still read it!
