Plotting of Line Graphs

Q. Following are the steps for plotting a line graph.

(a)	Plot the data points.
(b)	Connect the data points with straight lines.
(c)	Use a kink if actual data is far away from the starting value zero.
(d)	Determine the independent and dependent variables.
(e)	Choose the horizontal and vertical axis scale depending upon the minimum and maximum value of the independent and dependent variables, respectively.
(f)	Set the independent variable on the horizontal axis and the dependent variable on the vertical axis with appropriate units.

Arrange the steps in correct order.

1. $d\to f\to e\to c\to a\to b$
2. $a\to b\to d\to f\to e\to c$
