For every four minutes that pass, the balloon rises 200 feet.
For every four minutes that pass, the balloon rises 200 feet.

The balloon will be at 200 feet when it is launched.
The balloon will be at 200 feet when it is launched.

For every 2 minutes, the balloon rises 400 feet.
For every 2 minutes, the balloon rises 400 feet.

For every four minutes that pass, the balloon rises 400 feet.

Answer 1

To interpret the slope of the graph, we need to determine how much the height of the hot air balloon increases over a specific time interval.

If, for example, you can observe that the balloon rises 400 feet over a 4-minute interval, then the slope of the graph (which represents the rate of ascent) would indicate that:

For every four minutes that pass, the balloon rises 400 feet.

This response accurately describes the slope if that is what the graph represents.

So, based on the options provided, the correct interpretation of the slope would be:

For every four minutes that pass, the balloon rises 400 feet.
