Answer: The answer is given in the attached figure below.
Step-by-step explanation: Given that the ordered pairs (1,4), (3,12) and(5,20) represents the distance y the Dario walks after x seconds.
We are to plot the given ordered pairs in the co-ordinate plane and to draw a line through them.
As shown in the attached figure below, the distance y the Dario walks after x seconds is plotted on the co-ordinate plane.
The time in seconds is plotted across X axis and the corresponding distance walked by Dario is plotted across Y axis.
The point (1, 4) is represented by A, (3, 12) is represented by B and (5, 20) is represented by C.
Finally, we join the points A, B and C to make a straight line l.
Thus, the attached figure below is the required answer.
