Answer:

Slide the slide so as to increase the length of the air column that is resonating.

Explanation:

The relationship between the speed of sound, #v#; wavelength, #lambda#; and frequency, #f#, is
#v = lambda*f#.
If we assume that #v# is constant and if #f# is decreased, then #lambda# will be increased.
