Answer:
3
Step-by-step explanation:
Given
y = mx ( m is the constant of proportionality )
Given y = 12 when x = 4 , then
12 = 4m ( divide both sides by 4 )
3 = m ← constant of proportionality
Answer:
m = 3
Step-by-step explanation:
Find the constant of proportionality by plugging in x and y into the equation, and solving for m
y = mx
12 = m(4)
Divide each side by 4
3 = m
So, the constant of proportionality is 3
