No. It is a single number. For a direct variation you need a minimum of two pairs of ordered numbers.
one quantity varies directly as the square of the other quantity. in symbols, y = kx squared
If you are paid on an hourly rate, the number of hours that you work and your pay will be in direct variation.
direct varation is when both x and y rise and decrease by the same number. inverse is when x or y decreases, the other one increases by the same number
A direct variation (!) or direct reelationship.

No. Direct variation describes a relationship between two variables. It has nothing to do with the value of a single number.

Direct variation is not a special case.
Yes, it is direct variation.
No, it is not a direct variation.
I have recently been doing all these direct variation problems but not every linear relationship is a direct variation... But every direct variation is a linear relation!
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
Direct labor is direct cost as it varies with variation in production level and directly related with number of units of product.
