Answer:
y =7x , follows the direct variation.
Step-by-step explanation:
Direct variation states that a relationship between two variables in which one is a constant multiple of the other. In other words, when one variable changes the other changes in proportion to the first.
If y is directly proportional to x i.e, or
y = kx .....[1] where k is the constant variation
Given : y = 7x
On comparing this with equation [1] we get;
k(constant of variation) = 7
therefore,
it follows the direct variation as or
y = 7x where k =7 is the constant of variation.
Therefore, y =7x follows the direct variation.
