Determine whether each equation represents a direct variation. If it does, find the constant of variation.
To determine if the given equation represents a direct variation.
Answer to Problem 6P
The given equation does show a direct variation for its variables.
y increases with a constant variation of
Explanation of Solution
Given information:
Direct variation means when the given variables always have the same ratio. That is
Hence when equation is in a direct variation it can be written in form
Now let us check the given equation,
As the equation is in the form
Hence the given equation does show a direct variation for its variables.
y increases with a constant variation of
