Is the problem y equals 3x a direct variation if so what is the constant of variation?
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
What is the compares in constant and variable rate of change?
Tell whether the equation -4x+ 2y = -2 represents a direct variation. If so, identify the constant of variation.
How do you find the constant and slope for direct variation equations?
For a direct variation equation the constant MUST be 0. Then the ratio of a pair of values of the two variables is the slope.
Is the equation Y MX B a constant of variation?
No, it is a linear equation which does not pass through the origin unless B = 0. If B = 0 then Y and X could be said to vary in direct proportion and M would be the constant of variation, not the whole equation.
After determining if two quantities are in inverse or direct you can find the equation's constant by solving for it?
variation
What is constant of variation in math?
an equation of the form y = kx k is the constant of variation
What is the equation of an inverse relationship?
The equation is xy = k where k is the constant of variation. It can also be expressed y = k over x where k is the constant of variation.
Find the constant variation k for the inverse variation then write an equation for the inverse variation y 2.5 when x 9?
The equation is xy = 22.5

What is direct variation equation?
y = kx, where k is a constant, and x and y are the two variables.
Y varies inversely with x and the constant of variation is 6 what equation represents the relationship?
xY = 6.
What does an inverse variation equation look like?
y = k/x of xy = k where k is a constant.
What is the inverse variation equation?
Two variables, X and Y are said to be in inverse variation if XY = k or Y = k/X for some constant k.
