y = 5x
Step-by-step explanation:
Assuming you require the proportional equation
Given that y is directly proportional to x then the equation relating them is
y = kx β k is the constant of proportion
To find k use the condition when y = 30, x = 6 , then
30 = 6k ( divide both sides by 6 )
5 = k
y = 5x β equation of proportion
