Question

An airplane's altitude in feet during its descent can be found using the equation y=-150x + 30,500. After new government regulations become law, the descent isnow modeled by the equation y=-150x + 30,000. Which statement describes this change?
The airplane starts its descent from an altitude 500 feet lower.

The airplane descends 500 feet per horizontal mile slower.
