Answer:

see below

Explanation:

"y varies directly as x" -> y=kx (let k reprsent cov)

1. y=kx (substitute the x and y values into this)

16=k(4)

k=4

COV: k=4

Equation: y=4x

2. 9=k(3)

k=3

COV: k=3

Equation: y=3x

3. 12=k(3/5)

k=20

COV: k=20

Equation: y=20x

4. (here i am plugging in 2 for y and 620 for x because they're the smallest numbers)

2=k(620)

k=1/310

COV: k=1/310

Equation: y=1/310x

5. (here i am plugging in 25 for y and 1 for x)

25=k(1)

k=25

COV: k=25

Equation: y=25x
