Answer:
y=2x is an example of direct variation.
Step-by-step explanation:
Direct variation is mathematical relationship in between two variables which can be expressed by an equation where one variable is equal to a constant multiplied by the other variable.
In the equation y=2x, x and y are the variables and 2 is a constant.
Here it is expressed as an equation where the variable y is equal to the constant 2 multiplied by the other variable x.
Thus we can say that it is an example of direct variation.
