Question

The equation y − 160 = 40(x − 1) represents the height in feet, y, of a hot-air balloon x minutes after the pilot started her stopwatch.
a. Is the hot-air balloon rising or descending? Justify your answer.

Answer 1

Answer:

rising

Step-by-step explanation:

If x increases by 1 minute, then y increases by 40 feet. As time passes, the balloon gains altitude, so it is rising.
