A plane is flying at an altitude of 45,000 feet. It begins to drop in altitude 3,000 feet per minute. What is the slope in this situation?

Set up a graph where minutes is on the x-axis and altitude is on the y-axis.

1. Minute 1 = (1, 42,000)
2. Minute 2 = (2, 39,000)
3. Minute 3 = (3, 36,000)
4. Minute 4 = (4, 33,000)

You can see for every 1 unit move in x, we get a -3,000 unit move in y.

Pick any of these 2 points, and use our slope calculator to get:
Slope = -3,000
