False
A scatter plot would be best for non-related data points. A line graph would be best for related data points.

Scatterplot
To calculate an average using results from a graph, first identify the data points or values represented on the graph. Then, sum all the values and divide by the total number of data points. Ensure that you account for any relevant scale or units indicated on the graph. This will give you the average value represented by the data shown.
No, the best fit line need not go through any data point on a graph.
False
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.
A discrete graph.
Line graph...
they are called error bars. It represents the amount of error associated with each data point
linear graph
either a scatter graph or a line graph xx :)
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.
