is y= 1/2 x proportional relationship?

Answer 1

Yes, the equation \( y = \frac{1}{2}x \) represents a proportional relationship. In a proportional relationship, one quantity is a constant multiple of another. In this case, \( y \) is directly proportional to \( x \) with a constant of proportionality (also known as the constant ratio) of \( \frac{1}{2} \). This means that if you double the value of \( x \), \( y \) will also double, maintaining a consistent ratio.
