Answer:
y = [tex]\frac{63}{x}[/tex]
Step-by-step explanation:
Since y is inversely proportional to x the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportionality
To find k use the condition when y = 7, x = 9
k = yx = 7 × 9 = 63
y = [tex]\frac{63}{x}[/tex] ← equation connecting x and y
