Question

an elevator travels down from the top floor of a skyscraper. the graph below represents its height, in feet, over time in seconds. what is the meaning of the point (1, 525)?
answer
the height the elevator starts at. how long it takes for the elevator to reach the ground floor.
a height of 525 feet after one second. the rate of change in the elevators height over time.

Explanation:

In a coordinate system, the \(x -\)coordinate represents time (in seconds) and the \(y -\)coordinate represents height (in feet). For the point \((x,y)=(1,525)\), the \(x = 1\) means 1 second has passed, and the \(y=525\) means the height of the elevator at that time.

Answer:

A height of 525 feet after one second.
