Without the rest of the equation it is not possible to tell.

If the equation is in the form y = k*x where k is a non-zero constant, then it is.

Suppose the two variables are denoted by X and Y. If Y is a constant multiple of X, that is Y = c*X, then the variation is direct. If the value of X*Y is a constant, that is Y = c/X, then the variation in inverse.
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
y=x/7 y=(1/7) x It is a direct variation since it is of the form y=kx, where k=1/7 , a constant
A variable, Y, is in direct square variation with a variable, X, if Y = kX2 where k is some (non-zero) constant.
Yes, you can have a negative coefficient in a direct variation. So if you had y = -7x, that would be a direct variation. If you have y = -x, I do not know, if that is what you mean. Hope it helped.

No, y+2=x does not show direct variation. In direction variation you need to be able to multiply y by something to get x. In the question y+2=x, you have to add 2 to y to get x, which is not multiplying.)
y=3x is a direct variation in that y varies directly with x by a factor of 3. Any linear equation (a polynomial of degree 1, which is a polynomial equation with a highest exponent of 1), is a direct variation of y to x by some constant, and this constant is simply the coefficient of the "x" term. Other examples: y=(1/2)x is a direct variation, and the constant of variation is 1/2 y=-9x is a direct variation, and the constant of variation is -9
Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .
y=x/7 y=(1/7) x It is a direct variation since it is of the form y=kx, where k=1/7 , a constant
A variable y is said to be in direct variation with a variable x if there is a constant c (>0) such that y = c*x. c is called the constant of direct variation or proportionality.
x/y=k
It has a x and y intercept
No, this is an inverse variation.
