Find an equation for y in terms of x

Answer:
y = [tex]\frac{9}{x^2}[/tex]
Step-by-step explanation:
Given y is inversely proportional to x² then the equation relating them is
y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of proportion
To find k use an ordered pair from the table
Using x = 3 when y = 1 , then
1 = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )
9 = k
y = [tex]\frac{9}{x^2}[/tex] ← equation of proportion
