Question

Which equation has a constant of proportionality equal to 1? Choose 1 answer: 10 y = 11 7 y = 32 3. C y = 15

Answer 1

the constant of proportionality is the constant that multiplies the variable x

as we can see in the different options the only equation that the constant of proportionality is 1 is the option D.

y=x

Usually, we don't put the constant 1 when it is a constant of proportionality that is why we don't see the number one in this case.
