When the data on the graph is continuous,it does make sense to connect the points on the graph of 2 related variables.
A pair of two points (2D) or 3 points (3D) written as (x,y) or (x,y,z).
To graph points, use rise over run and go up and over on the graph
It is a graph of isolated points - nothing more, nothing less!
No correlation. Answer provided by
With only two points you don't know the direction of the graph. Drawing a graph using only two points can result in the diagram being wrong.
Connect the two points.
The distance covered between two points in time is the area under the graph between the two points.

Creating a line graph is a simple thing to do. If you have two points, you can create a line graph.
A line graph.
A pair of two points (2D) or 3 points (3D) written as (x,y) or (x,y,z).
a graph that uses two lines connected by points to show value
Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
You should always use the vertex and at least two points to graph each quadratic equation. A good choice for two points are the intercepts of the quadratic equation.
-- Pick two points on the graph. -- Find the difference in time between the two points. -- Find the difference in displacement between the same two points. -- (Difference in displacement) divided by (difference in time) is the average Speed . You can't tell anything about velocity from the graph except its magnitude, because the graph displays no information regarding the direction of motion.
(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.
