Kendall runs at a speed of 12 yards per second. To identify the correct line, we need to find the line that shows a distance of 12 yards for every second.

• At 1 second, Kendall should be at 12 yards.
• At 2 seconds, Kendall should be at 24 yards.
• At 3 seconds, Kendall should be at 36 yards.
• At 4 seconds, Kendall should be at 48 yards.
  Line B matches these points, indicating Kendall's run.

Supplemental Knowledge

In algebra, the relationship between two variables can often be represented by a linear equation of the form \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept. The slope represents the rate of change, which in this case is Kendall's running speed (12 yards per second). The graph of this equation will be a straight line where the slope indicates how steeply the line rises.

Life in Context

Imagine you're tracking your running progress over time by plotting distance against time on a graph; by do so you're able to visually observe changes and improvements to speed and form. This concept has many other applications in various disciplines such as physics for understanding motion; economics to monitor trends; project management as a means for tracking project progression over time and so forth.
