The point-slope form of an equation of a line is:


y-b=m(x-a)

Where m is the slope and (a,b) is a point through which the line passes. Here we are told that the slope is -1/5 and the point through which the line passes is (-7,9). Then we must make the following replacements:


\begin{gathered} m=-(1)/(5) \\ a=-7 \\ b=9 \end{gathered}

Then, the equation of the line in point-slope form is:


y-9=-(1)/(5)(x+7)

And that is the answer to this question.
