Which equation can be used to describe the direct variation?
Hereof, which equation is a direct variation function?
Direct variation function is defined as the relation where one variable vary constant times to the other variable. let two variables are x and y. y = kx where k is constant. y = x is direct variation function where k = 1.
Also Know, what is another name for direct variation? Direct Variation. Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).
Beside this, which 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.
How do you solve for direct variation in K?
Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
