An example of a variation equation would be the formula for the area of the circle: . In the language of variation, "the area A varies directly with the square of the radius r"; the constant of variation is . This formula is an example of "direct" variation.

If y varies directly as x, the graph of all points that describe this relationship is a line going through the origin (0, 0) whose slope is called the constant of the variation. That's because each of the variables is a constant multiple of the other.

In direct variation we say that y varies directly with x or y varies directly as x. In the direct variation equation, y kx, k is the constant of variation. The constant of variation in a direct variation equation has the same value as the slope of the graph.

constant of variation, slope of the line, 3x: Hi, First of all, the constant of variation is always going to be the number that is attached to the x. In the first problem, it is -2, the second is 3, and the last one is (3/2). The slope for each pair of points is going to be the same number as the... ... More Algebra Answers;
