30 points! (question is located in picture under graph) a) the variables are plotted along incorrect axes. b) the unit of the variable on the y-axis is incorrect. c) the scale for each axis is not appropriate for the data. d) the data points have not been plotted clearly. e) the data points have not been plotted accurately.

B) The unit of the variable on the y-axis is incorrect.

Explanation:

The question to this exercise is in the picture. It is '' What makes the above graph incorrect? ''

Let's analize each option :

A) The variables are plotted along incorrect axes. This is wrong because actually the graph is well-plotted. In a displacement versus time graph we put the time variable in the x-axis and the displacement variable in the y-axis.

B) The unit of the variable on the y-axis is incorrect. This is true. In the graph we can see that when the units of displacement are units of lengths such as meters or miles for example. Therefore, the B) is a correct option

C) The scale for each axis is not appropriate for the data. This is wrong. Because of the scale for each axis we are able to see the five  data points which are (1,2) ; (2,4) ; (3,6) ; (4,8) and (5,10)

D) The data points have not been plotted clearly. This is wrong. All data points are well-plotted signposted with a point at the intersection of the dashed coordinated lines. For example, the point (1,2) is at the intersection of two lines : one dashed line perpedicular to the x-axis at 1 and one dashed line perpendicular to the y-axis at 2

E) The data points have not been plotted accurately. This is wrong. The data points have been plotted accurately at the intersection of the coordinated dashed lines.

Finally, the only correct option is B)

answer: decibel
