Inversely Proportional

y is inversely proportional to x when x =3, y = 8 work out the value of y when x = 8

y is inversely proportional to x: yx = k, such k is constant

Did you know?

  • Inversely proportional is also known as inverse variation.

Given:

  • x = 3
  • y = 8

To determine the constant of variation, substitute the first two given values to the equation of variation.

  • yx = k
  • (8)(3) = k
  • 24 = k

To determine the value of y, substitute the second given value of x including the constant of variation.

  • x = 8, y = ?
  • yx = 24
  • 8y = 24
  • y = 24/8
  • y = 3

Answer:

  • The value of y is 3.
