You don't really ever have to, but doing so makes analyzing data and explaining certain mathematical concepts much easier. For instance, in calculus, a graphical interpretation of a derivative is "the slope of the curve at any point" and an integral's interpretation is "the area under the curve between two points."
If the variables are something continuous, then you should connect the points. For example, if it is your height and weight then since those variables are continuous it is necessary to connect the points plotted on the coordinate graph.
that depends on what you are trying to do
(it makes sense to connect the points on a graph wen there is movement....or so u can see it more cearly)--BreeBree..... hope i helped!! OR you could connect the points when it is a continuous thing.
It makes sense to connect the points on a graph when the variable ont the x axis (bottom line) is able to be split, ex. time

When the data on the graph is continuous,it does make sense to connect the points on the graph of 2 related variables.
If the variables are something continuous, then you should connect the points. For example, if it is your height and weight then since those variables are continuous it is necessary to connect the points plotted on the coordinate graph.

No.If the points on the graph are connected then they are already connected so it would be complete waste of time to connect them.
Because their is no lines on the graph to connect the point.

You connect them because you want to Show the increase and Decrease

Connect the two points.
the points on a bar graph are not connected to each other.
