Question

What is the constant of proportionality in the equation?

y = 5 x
0
1
4
5

Answer 1

In the equation \( y = 5x \), the constant of proportionality is the coefficient of \( x \).

Here, the coefficient is \( 5 \). This means that for every unit increase in \( x \), \( y \) increases by \( 5 \) units.

So, the constant of proportionality is **5**.
