if x varies inversely as y then xy is a constant (k)
eg if x doubles as y halves then examples are:
x = 6, y = any then k = 6y
when x = 12, y = any/2 then k = 12/2 times any ie 6y.

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 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.
What is inverse variation?
Two variables, x and y are in inverse variation if x*y = c for some constant c. The equation can be written in the form y = c/x.
Suppose that y varies with x Write an equation for the inverse variation y 4 when x 7?
If y varies with x, then there cannot be an inverse variation between x and y!
What is the inverse variation?
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.
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
The equation y 8x is an example of inverse variation is this true?
No. This is not true. It is false. The equation is an example of direct variation.
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.
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.
What is inverse variation?
Two variables, x and y are in inverse variation if x*y = c for some constant c. The equation can be written in the form y = c/x.
After determining if two quantities are in inverse or direct you can find the equation's constant by solving for it?

What does an inverse variation equation look like?
y = k/x of xy = k where k is a constant.

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.
How do you do a direct variation with an inverse variation problem?
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
Find the inverse variation equation if x equals 5 when y equals 9?
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
Does the graph of an inverse variation pass through the origin?
Inverse variation does not pass through the origin, however direct variation always passes through the origin.
