Explanation: 

Detailed explanation-1: -The most used graph for visualizing the relationship between two numeric variables is the scatter plot.

Detailed explanation-2: -Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

Detailed explanation-3: -Definition. A line chart or line graph displays the evolution of one or several numeric variables. Data points are connected by straight line segments. It is similar to a scatter plot except that the measurement points are ordered (typically by their x-axis value) and joined with straight line segments.

Detailed explanation-4: -A scatter plot displays the relationship between 2 numeric variables. A correlation coefficient calculation measure the strength of the relationship between the variables. For each data point, plot the value of its first variable on the X axis and the second variable on the Y axis.
