Question

explain direct variation with example ( minimum 2 questions solutions)​

Answer 1

Answer:

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. ... As previously stated, k is constant for every point; i.e., the ratio between the y-coordinate of a point and the x-coordinate of a point is constant.
