Answer:
see explanation
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition
x = 2 when y = 2
k = yx = 2 × 2 = 4, hence
y = [tex]\frac{4}{x}[/tex] ← equation of variation
