use the drop-down menus to complete each sentence.
in section a, speed is as time is increasing.
in section b, speed is as time is increasing.
in section c, speed is as time is increasing.
in section d, speed is as time is increasing.

chart: speed (mph) on y-axis, time (minutes) on x-axis, with sections a, b, c, d plotted

Explanation:

• Section A: The line slopes downward, so speed falls as time passes.
• Section B: The line is flat at 0, so speed does not change.
• Section C: The line slopes upward, so speed rises as time passes.
• Section D: The line is flat at a positive value, so speed stays steady.

Answer:

In section A, speed is decreasing as time is increasing.
In section B, speed is constant (at 0 mph) as time is increasing.
In section C, speed is increasing as time is increasing.
In section D, speed is constant (at a steady non-zero value) as time is increasing.
