Answer:

The equation for the relationship is
y=(7)/(2) * x.

Explanation:

Given that point
(x,y)=(6,21) is part of a direct relationship. That is:


y \ \infty \ x


y=k* x (1)

Where
k is the proportionality constant.

If we know that
x=6 and
y=21, then the proportionality constant is:


k=(y)/(x)


k=(21)/(6)


k=(7)/(2)

Lastly, the equation for the relationship is
y=(7)/(2) * x.
