Find the k (constant of proportionality)

Answer:
k = 1.5
Step-by-step explanation:
For 2 quantities in direct proportion the constant of proportionality k is
k = [tex]\frac{y}{x}[/tex]
Using the ordered pairs from the table , then
k = [tex]\frac{3}{2}[/tex] = [tex]\frac{12}{8}[/tex] = [tex]\frac{15}{10}[/tex] = [tex]\frac{36}{24}[/tex] = 1.5
