Direct Variation:
A function in the form y = kx, where k is the constant of variation
You can say that y varies directly as x
A direct variation must also pass through the origin ie) if x=0 then y=0
y y
k  1 and k  2 1  2
x2 x1 x2
k is also called the constant of proportionality, and y is said to be directly
proportional to x
y1 y2
x1 x2
Inverse Variation:
Is a function defined by an equation of the
,where x  0
You can say that y varies inversely as x or that y is inversely proportional to x
k is the constant of variation
x1 y1  x2 y2
form: xy  k , where k is a non-zero constant or y=
