The variables are the alphabets which can have any value depending on the relationship with the other numbers and variables in the equations.
To create the graph, select the correct relationship and then enter the values for the variables.
The graph is the representation of the equation in the form of lines or shapes.
The correct method to create a graph is to find the relationship of the variables and put their values to get the exact points.
The points are joined together to draw the required line or shape formed.
The best option of the given question is:
To create the graph, select the correct relationship and then enter the values for the variables.
For example in the given graph we see that the rate is increasing as the mass is decreasing.
The mass is plotted along x-axis and the <em>rate</em> along the <u><em>y-axis.</em></u>
Their relationship that they are <em><u>inversely proportional</u></em> i.e. one increases as the other decreases can be seen in the given graph.
