How Do You Find the Constant of Variation from a Direct Variation Equation?

To find the constant of variation, we have to see if our equation of y=2x looks like the equation for direct variation
The equation for direct variation is y=kx
k is the constant of variation
The y's are in the same place in each equation
The x's are also in the same place in each equation
The constant of variation (k) is the number in front of the x, which is 2

1. We were given the equation y=2x
1. We need to find the constant of variation for this equation
1. We need to find the constant of variation for y=2x
1. A direct variation equation looks like y=kx
1. k is the constant of variation
1. Our equation is y=2x
2. We want to know if our equation looks like the equation for direct variation, y=kx
1. Our equation y=2x looks like the equation for direct variation, y=kx
1. Our equation y=2x looks like the equation for direct variation, y=kx
1. k is the constant of variation
1. Since the y's and the x's are on the correct sides, we should be able to find the constant of variation (k) more easily
1. k is the constant of variation
1. This means that 2 is our constant of variation (k)
2. Our equation is y=2x
1. This means that 2 is our constant of variation (k)
2. Our equation is y=2x
3. The constant of variation is the coefficient in front of x
