Question

This table represents a proportional relationship. x 3 5 7 11 y 4.5 7.5 10.5 16.5 What is the constant of proportionality for the relationship? 23 32 2 I don't know.

Answer

2

  • Identify two values for x and y. A: x=3, y=4.5
  • Identify a second set of values for x and y. A: x=5, y=7.5
  • Use the two sets of values to find the constant of proportionality. A: The constant of proportionality (k) is found using the formula k = y / x: k = 4.5 / 3 = 1.5 and k = 7.5 / 5 = 1.5.
