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

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Can ax plus by equals c be a direct variation if a and b and c does not equal 0?

No, direct variation is "y=ax." In direct variation a equals any real constant, b=1, and c must equal zero. If any of thee conditions are changed, it is not direct variation.

What does constant of variation mean?

It means if it is the constant rate of a number kind of like a direct variation. Like if you say 10 divided by 5 it equals 2 and if you say 4 divided by 2 it equals 2 so that's constant I hope I could help you

No, this is an inverse variation.


Is -3x - 35y equals 14 a direct variation?

no. direct variation implies that you can simplify the problem into several forma which are equivalent to y/x = k in which k is called the constant of variation. one of these equivalent forms would by y = kx + 0 (slope intercept form) in which the y intercept must be 0 rearranging your equation gives a y- intecept of -14/35 which reduces to -2/5 since this is not zero. this is not direct variation.
