Answer:
y = [tex]\frac{12}{x}[/tex]
Step-by-step explanation:
given y is inversely proportional to x, then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportionality
to find k , substitute y = 4, x = 3 into the equation
4 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
12 = k
y = [tex]\frac{12}{x}[/tex] ← equation of proportion
