An airplane 45,000 feet above the ground begins descending at a rate of 1,500 feet per minute. Which equation represents the relationship between t, the number of minutes of descent, and h, the height above the ground?

• h = 1,500t + 45,000

• h = 1,500 + 45,000t

• h = -1,500t + 45,000

• h = 1,500 - 45,00t0
