if the point (2,4) lies o the graph of a direct variation what is the constant of variation

Answer 1

The constant of variation for direct variation is the ratio of the y-coordinate to the x-coordinate for any point on the graph.

Given that the point (2,4) lies on the graph of a direct variation, the constant of variation can be found by using the formula:

constant of variation = y-coordinate / x-coordinate

constant of variation = 4 / 2 = 2

Therefore, the constant of variation for the given point is 2.
