Direct Variation Quiz

What is the main topic discussed in the video?

• Indirect Variation

• Direct Variation

• Linear Equations

• Inverse Proportion

In the first example, what is the relationship between y and x?

• y is inversely proportional to x

• y is directly proportional to x

• y is equal to x squared

• y is a constant

What is the general formula for direct variation?

• y = k + x

• y = kx

• y = x/k

• y = k - x

How do you find the constant of variation (k) in the first example?

• By subtracting x from y

• By multiplying x and y

• By dividing y by x

• By adding x and y

What is the value of x when y is 30 in the first example?

• 12.5

• 15

• 10

• 20

In the second example, what is the initial value of y when x is 15?

• 5/2

• 1/6

• 3

• 10

What is the constant of variation (k) in the second example?
