Answer:

Yes the equation is a direct variation.

There is no constant variation in this equation.

Step-by-step explanation:

[tex]\frac{2}{3}x =\frac{8}{5}y[/tex]

y = (2 × 5)x / (3 × 8) = 10/24x

Simplified gives:

y = 5/12x

Therefore y is directly proportional to x and the factor of the variation is 5/12.

There is no constant in this direct variation equation.
