Answer:

5

Step-by-step explanation:

Remember that the slope of a line that is perpendicular to a given line is the negative reciprocal of the slope of the given line.

Here we are given the line y = -(1/5)x - 9.  The slope is (-1/5).  The negative reciprocal of this is +5.  That's the answer you wanted.
