If it's always negative, no matter what interval we are looking at, we can conclude that the graph is always sloped downward, or decreasing, from left to right.
Its the third option y-9=-1/4(x+2) because the equation for point slope form is y-y1= m(x-x1) so because there is a negative 2 it is a positive 2. Remember a negative minus a negative is a positive. Hope this helped :)!
