Question 4(Multiple Choice Worth 1 points)
(02.03 MC)
The graph shows the velocity f(t) of a runner during a certain time interval:
Graph of line segment going through ordered pairs 0, 2 and 6, 8. Graph of another line segment going through ordered pairs 6, 8 and 8, 0. Label on the x axis is time in seconds, and label on the y axis is velocity in meters per second.
Which of the following describes the intercepts on the graph?
the intercepts are where x or y is zero.
So, ...
extra credit: How far did she run during that time?
The intercepts on the graph can be described as follows:
1. X-intercept: The x-intercept is the point where the graph intersects the x-axis. In this case, the x-intercept is at (8, 0), which means that at 8 seconds, the runner's velocity is 0 meters per second.
2. Y-intercept: The y-intercept is the point where the graph intersects the y-axis. In this case, the y-intercept is at (0, 2), which means that at 0 seconds, the runner's velocity is 2 meters per second.
To determine the intercepts on the graph, we need to look at where the graph crosses the x-axis and the y-axis. The x-axis represents time in seconds, and the y-axis represents velocity in meters per second.
From the graph, we can see that the line segment goes through the ordered pairs (0, 2) and (6, 8). This means that at time t = 0 seconds, the velocity is 2 meters per second, and at time t = 6 seconds, the velocity is 8 meters per second.
Similarly, the graph also goes through the ordered pairs (6, 8) and (8, 0). This means that at time t = 6 seconds, the velocity is 8 meters per second, and at time t = 8 seconds, the velocity is 0 meters per second.
Therefore, the intercept on the x-axis is at t = 8 seconds, and the intercept on the y-axis is at v = 0 meters per second.
The correct answer is: The intercept on the x-axis is 8 and the intercept on the y-axis is 0.
VERY incomplete!
