A scatter plot would be best for non-related data points. A line graph would be best for related data points.
To get data from a graph efficiently, you can use the gridlines and labels on the axes to determine the values of the data points. You can also use a ruler or a straight edge to help you accurately read the data points from the graph.

Maths
It depends on what you are trying to do.
A line graph is used to display data over time with points connected by lines. This type of graph highlights trends and patterns in the data.
