DIRECT VARIATION
PASS OUT FLAT FOLDABLE
We will be looking to see if there is a direct relationship in different sets of data. If the constant of proportionality (now called constant of variation) is the same for all data given, the data is related through a direct variation.
The graph of a direct variation always passes through the origin; therefore, represents a proportional relationship.
DIRECT VARIATION CAN BE WRITTEN
y = kx
CONSTANT OF PROPORTIONALITY CONSTANT OF VARIATION SAME THING Can be written
= k
