k = 5: direct proportion confirmed.

  • For every 1-unit increase in x, y changes by 5. The relationship is y = 5x.
  • The ratio y/x is constant at 5 for every pair of corresponding values.
  • Since k > 1, y grows faster than x.

Next stepUse the table of values below to verify the relationship across a range of x values.
