Answer:
Explanation:
It is 1. Any coefficient in front of x in an equation like
y = kx
is just k. So for y = 14x the constant of proportionality is just 14. Negatives after much debate, can also be constants of proportionality
y = - 5x
The constant of proportionality is - 5
The general equation cannot be y = kx + b where b is not equal to zero does not have a constant of proportionality although it looks like it should.
