Tracie rides the bus home from school each day. The graph represents her distance from home relative to the number of minutes since the bus left the school.

1. Tracie's bus travels towards her home at an average speed of  miles per minute.

Step-by-step explanation:

From the graph, we see that,

X-axis represents the time (in minutes) and the Y-axis represents the distance from home (in miles).

Also, the graph of the function is decreasing by 1 miles for every 2 minutes.

That is, the distance from home is decreasing as the time increases.

That is, the bus is getting closer to the home.

Further, as the distance is decreasing by 1 mile for every 2 minutes.

Thus, the rate of decrease is  miles per minute.

As we know,

So, the slope represents the speed of the bus travelling towards home.

That is, 'Tracie's bus travels towards her home at an average speed of  miles per minute'.
