Answer:
a
Step-by-step explanation:
The equation of a proportional relationship is
y = kx ← k is the constant of proportionality
Divide both sides by x
[tex]\frac{y}{x}[/tex] = k
To find k use any ordered pair from the table
Using (2, [tex]\frac{5}{2}[/tex] ) , then
k = [tex]\frac{2}{\frac{5}{2} }[/tex] = 2 × [tex]\frac{2}{5}[/tex] = [tex]\frac{4}{5}[/tex]
