Answer:
Please check the explanation.
Step-by-step explanation:
If the ratio y/x is the same for all related pairs of x and y, it means it represents a proportional relationship.
In other words, '
' varies proportionally with '
' or that '
' is directly proportional to '
'.
When we say the ratio is the same, it means when '
' increases, '
' increases and as '
' decreases, '
' decreases
Using the equation
y ∝ x
y = kx
k = y/x
Where 'k' is the proportionality constant.
