For a direct variation describe how the constant of variation affects whether y increases or decreases as x increases
Goryan [66]
Direct variation is of the form: y=kx  (inverse variation is of the form y=k/x)

Assuming that k is positive :)

y increases as x increases and y decreases as x decreases.  There is a direct ratio that is described by k.  k=y/x.

u can convert that to 9/2
then to get the reciprocal you flip the denominator and numerator
this gives u 2/9
