Question

2. Find the variation constant and an equation of variation where y varies inversely as x and y=9 when x=2.

Answer 1

Answer: y=108

Explanation:

Answer 2

k = 4.5

y = 4.5x

Explanation:

Finding the variation constant, k :

• k = y/x
• k = 9/2
• k = 4.5

Equation of variation :

• y = kx
• y = 4.5x
