We know that the equation of the line is in the form
. To find b, we can use the fact that (6,-5) lies on the line, meaning that both sides of the equation are equal when x=6 and y=-5.

Hence, the equation of the line is
, and its graph looks something like follows.

in log multiplication means addition
hence we add giving us
