If the height of a plane 125 seconds after takeoff is 400 feet, which point represents this on the graph?

• (125, 125)

• (125, 400)

• (400, 125)

• (400, 400)

Why is time not a function of the plane's height?

• Time can have multiple values for one height

• Height varies too much

• Time is always constant

• Height cannot be measured accurately
