The equation for the relationship is $y = \frac{7}{2}\cdot x$ .

Step-by-step explanation:

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

$y \propto x$

$y = k\cdot x$ (1)

Where is the proportionality constant.

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

$k = \frac{y}{x}$

$k = \frac{21}{6}$

$k = \frac{7}{2}$

Lastly, the equation for the relationship is $y = \frac{7}{2}\cdot x$ .
