There are many types of questions that can be asked about graphs, but some of the most common questions are those that ask about the nature of the graph itself. For example, questions might ask about the overall shape of the graph, whether it is increasing or decreasing, or how quickly it is changing. Other questions might ask about specific points on the graph, such as what the coordinates of a particular point are, or whether two line segments intersect. Still other questions might ask about trends that can be seen in the graph, such as whether a graph is linear or nonlinear.
