Constant Variation and Direct Variation

Determine if the relationship between the two quantities is a direct variation. Explain your reasoning.

• yes, the constant of variation is 1/2

• yes, the constant of variation is 2

• no, there is constant of variation.

Determine if the relationship between the two quantities is a direct variation. Explain your reasoning.

• yes, the constant of variation is 8.

• no, there is no constant of variation

• yes, the constant of variation is 1/8

Determine if the relationship between the two quantities is a direct variation. Explain your reasoning.

• yes, the constant of variation is 2

• yes, the constant of variation is 1/2

• no, there is no constant of variation

Determine if there is a constant of variation. If so, explain what it represents. The equation y = 24 x represents the number of bottles of water y in x packages.

• The constant of variation is 24. This means that there are 24 bottles of water in each package.

• There is no constant of variation. The number of bottles varies per package.

Is the given table a direct variation? If so, what is the constant of variation?

• Yes; 1/3

• Yes; 3

• Yes; 5

• No

Y varies directly as x. If y = 12 when x = 15, what is y when x = 20?

• 4/5

• 17

• 16

• 25

n varies directly with c. If c = 24 when n = 18, what is c when n = 22?

• 88/3

• 28

• 66/4

• 24

What is the constant of variation (k)?

• 8

• 16

• 24

• 2

Find the constant, or the k in the data. Note, y = kx

• k = 10

• k = 5

• k = 4

• k = 2

For Box E, find the "k"

• k= -5

• k= -.05

• k= -0.2

• Cannot solve for K
