What equation is an example of direct variation?
For example, if y varies directly as x, and y x3d 6 when x x3d 2, the constant of variation is k x3d x3d 3. Thus, the equation describing this direct variation is y x3d 3x
What equation represents the variation?
Explanation: For direct variation we have: yx3dkx where k is the constant of variation.
What is an example of a direct variation?
Some examples of direct variation problems in real life: The number of hours you work and the amount of your paycheck. The amount of weight on a spring and the distance the spring will stretch. The speed of a car and the distance traveled in a certain amount of time.
What is the equation form of a direct variation?
The general form of a direct variation formula is y x3d k x yx3dkx yx3dkx, where x and y are variables (numbers that change) and k is a constant (a number that stays the same).
What is direct variation give 2 examples?
Direct Variation is said to be the relationship between two variables in which one is a constant multiple of the other. For example, when one variable changes the other, then they are said to be in proportion. If b is directly proportional to a the equation is of the form b x3d ka (where k is a constant).
Which shows an example of direct variation?
Some examples of direct variation problems in real life: The number of hours you work and the amount of your paycheck. The amount of weight on a spring and the distance the spring will stretch. The speed of a car and the distance traveled in a certain amount of time.
What is a direct variation in math?
Definition of direct variation 1 : mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other. 2 : an equation or function expressing direct variation u2014 compare inverse variation.
How do you write a variation equation?
For example, if y varies directly as x, and y x3d 6 when x x3d 2, the constant of variation is k x3d x3d 3. Thus, the equation describing this direct variation is y x3d 3x

Direct and Inverse Variation: Applications of Inverse Variation
- The bank balance is inversely proportional to spending.
- The number of family members (who do not work) is inversely proportional to savings.
- The working days required to complete the work are inversely proportional to the number of labourers.
