Answer:
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,
<em>So, the slope represents the speed of the bus travelling towards home.</em>
That is, 'Tracie's bus travels towards her home at an average speed of miles per minute'.
