xY = 6.
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.
The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
The inverse variation is the indirect relationship between two variables. The form of the inverse variation is xy = k where k is any real constant.

2=8/4 the constant is 8 y-k/x i think.
yes y=kx is the formula for direct variation, and k represents constant of variation which can also be called slope.
Constant variation is a relationship between two variables where one is a fixed multiple of the other. The graph of such a relationship is a straight line through the origin.
Direct variation.
Yes, the equation ( y = -3x ) represents a direct variation. In a direct variation, the relationship between two variables can be expressed in the form ( y = kx ), where ( k ) is a constant. Here, the constant ( k ) is -3, indicating that ( y ) varies directly with ( x ) but in the opposite direction.
Inversely proportional.
they are inversely proportional when the speed of the wave is constant
If the product of two variables is equal to a constant, then they are inversely proportional. eg. If xy=c where c is a constant, then x and y are inversely proportional.
Tell whether the equation -4x+ 2y = -2 represents a direct variation. If so, identify the constant of variation.
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 .
The relationship between two variables whose ration is a constant value is a directly proportional relationship. An example of this is the ideal gas law, PV = nRT. Pressure and volume are directly proportional to the number of molecules of an ideal gas present ad the temperature.
Boyle's Law states that the pressure of a gas is inversely proportional to its volume, when the temperature is held constant. Mathematically, this relationship is expressed as P1V1 = P2V2, where P represents pressure and V represents volume.
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.
