Answer:

Proportional relationship formula:

  • y = kx, where k is the constant of proportionality

Use one of the ordered pairs to calculate the value of k

Company A

Point (2, 20)

  • 20 = k*2
  • h = 20/2
  • k = 10

The equation: y = 10h

Company B

Point (3, 20)

  • 20 = k*3
  • k = 20/3
  • The equation: y = 20/3h

Company A has greater unit rate as 10 > 20/3
