2. Find the constant of variation k for the inverse variation. Then write an equation for the inverse variation. y = 4.5 when x = 3
a. k = 13.5; xy = 13.5
b. k = 1.5; y = 1.5
x
c. k = 1.5; y = 1.5x
d. k = 13,5; 13.5y = x

Correct choice: a. k = 13.5; xy = 13.5

Step-by-step explanation:

Inverse Proportion

Two variables x and y are in inverse proportion or variation if:

Where k is the constant of proportionality

Since we know that y=4.5 when x=3:

Solving for k:

Thus the equation is:

Or, equivalently:

Correct choice: a. k = 13.5; xy = 13.5
