Answer:

Option C)
\displaystyle(y)/(x)

Explanation:

Proportional relationship:

  • Proportional relationships are relationships between two variables where their ratios are equivalent.
  • In a proportional relationship, one variable is always a constant value times the other.

  • y \propto x\\y = ax\\\\\displaystyle(y)/(x) = a

Thus, from a proportional graph, constant rate of change can be calculated with the help of ratio of y and x.

Option C)
(y)/(x)

can be used to calculate constant rate of change,
