Two equations for the constant of proportionality equal to 1/2
NemiM [27]

y=kx and y=\frac{k}{x} are two equations of constant of proportionality

Step-by-step explanation:

          There are two equations for the constant of proportionality. That is

                       (i) Direct proportion

                       (ii) Inverse proportion

          In direct proportion y=kx, Now

                  if x increases, then y also increases and if x decreases, then y also decreases. So, k is a constant proportionality.

         In Inverse proportion y=\frac{k}{x}, Now

                 if x increases then y decreases and if x decreases, then y increases and k is a constant proportionality.

         In direct proportion, we put y=1 and x=2, So k=\frac{1}{2}.

         So, the equations y=kx and y=\frac{k}{x} are two equations of constant of proportionality.
