Answer:


y = x \\ the \: constant \: k \: will \: be \: y = kx \\ therefore \: if \: y = 9 \: and \: x = 1 \\ the \: equation \: will \: be \: 9 = k(1) \\ this \: gives \: k = 9 \\ therefore \: to \: represent \: in \: equation \: it \: will \: be \\ y = 9x

Answer:

k = 9

y = 9x

Explanation:

Variation Constant Formula :

  • k = y/x
  • k = 9/1
  • k = 9

Equation :

  • y = kx
  • y = 9x
