Anyway, a straight line through the origin (0,0) always represents a direct variation between y and x. The slope of this line is the constant of variation. In other words, in the equation y=mx y = m x , m is the constant of variation.
What represents direct variation?
In other words, the ratio between the two variables in a direct variation is constant. A direct-variation relationship can be represented with an equation of the form y = kx, where k is the constant of variation.
Which of the following is an example of 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. The speed of a car and the distance traveled in a certain amount of time.
