Anyone of them is fine. It doesn't really matter.
You would use a bar graph is useful when the independent variable (x-variable) is categorical. But there are no hard and fast rules. If it conveys the relevant information effectively then use it and if not don't.
a simple 2d xy line graph has only the possibility for 2 different variables (x and y). for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs.
It can be, but not necessarily. If I had the heights (continuous variable) of a class of students I might use a histogram. Conversely, if I had the number of cars (discrete variable) driving by every minute, I would use a line graph. It all depends on which kind of graph conveys the information to your audience in the best way.
it depends on what kind of data you are desplaying. if there is only one type of data that is all related and conected, a line graph would be a good thing to use.
The type of graph you would use would be a PICTURE GRAPH or a TALLY CHART
line graph
Line Graph.
Most likely a bar or pie graph
a collumn graph
The horizontal axis.
probably orographic bar graph would work the best!
On a distance vs. time graph, time is usually the independent variable presented on the X axis in the Cartesian Coordinate System. The dependent variable would be distance, and would be presented on the Y axis.
If a body is moving with variable speed, then the only thing you can say aboutits speed/time graph is that the graph is not a straight, horizontal line.
We would need to see the graph to respond to this question.
The slope of a position/time graph is the speed (magnitude of velocity).If the graph's slope is changing, that means the speed is changing, andthat would be accelerated motion.
