Answer:
Step-by-step explanation:
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 ofvariation is k = = 3. Thus, the equation describing thisdirect variation is y = 3x.

Answer:
Step-by-step explanation:
The general equation for direct variation is the linear equation, y = kx where k is the constant of variation (or constant of proportion). The constant of variation is also the slope of the line representing the relationship between input and output.
