Y=0.25x

Question

What is the constant of proportionality

Answer 1

In the equation \( Y = 0.25x \), the constant of proportionality is the coefficient of \( x \).

Here, the constant of proportionality \( k \) is \( 0.25 \). This means that for every 1 unit increase in \( x \), \( Y \) increases by 0.25 units.
