Question

Is the expression of y=1/7x and example of direct variation? If, yes then what is the constant of a variation

Answer 1

Direct Variation. 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. Step-by-step explanation:

Answer 2

direct variation

constant = 1/7

Explanation:

The equation for direct variation is

y = kx

y = 1/7 x is in this form with the constant of variation being 1/7
