Answer:
The graph is attached below.
Step-by-step explanation:
Given:
Zahra runs a 800-meter race at a constant speed.
Race starts from the finish line.
Finish line is at a distance of 800 m from the starting point.
Time is plotted on the x axis and Distance is plotted on the y axis.
So, the graph must start from the [tex]800^{th}[/tex] mark on the y axis when time is 0.
Now, the speed is constant which means that the slope of the line of distance versus time is a straight line because,
Speed [tex]=\frac{Distance}{TIme}[/tex].
Now, the graph should have the following properties:
1. Starting point of the graph should be (0, 800).
2. Final point of the graph should be (t, 0).
3. Slope should be constant everywhere. So, the graph must be a straight line.
Thus, the graph is a line joining the points (0, 800) and (t, 0) as shown below.
