Stack plot.
The line of best fit is found by statistical calculations which this site is too crude for. Look up least squares regression equation if you really wish to follow up. The slope of a graph is the slope of the tangent to the graph curve at the point in question. If the function of the graph is y = f(x) then this is the limit, as dx tends to 0, of [f(x + dx) - f(x)]/dx.
In general, it is impossible. You could try putting together a data set using as many of the points as possible from the graph. Then try various regressions. You may have to perform transformations on the data if the function rule is not straightforward. This could require some very high level statistical techniques. You could be lucky and the graph is a straight line!

A multivariate graph.
Error bars are often used on graphs to show statistical comparisons.
line graph and histogram
bar graph,histogram and frequency polygon are the three basic forms of statistical representation
A Co-relational statistical procedure is a technique used to know the relationship between two variables or measures the closeness of two statistical data. A statistical graph is the best representation of it.
There is no such figure.
Contour map
A table can be used, or various types of graph. Sometimes a simple sentence is enough.
LINE GRAPHS - is a common statistical graphs for expressing trends (that is, decreases / increases and how fast / slow) over a specified period of time.
