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.
Starting from the fundamental trigonometric equation, we have
Since , we know that the angle lies in the third quadrant, where both sine and cosine are negative. So, in this specific case, we have
Plugging the numbers, we have
Now, just recall that
to deduce
