I am sorry but this question refers to a particular graph and the graph or a reference to it was not included.
A bar graph is information that is collected by counting can be displayed on this graph. A pie graph is a graph that shows information as parts of a circle
The general formula for a cubic graph is y=ax3 + bx2 + cx + d.
The answer depends on what type of information is contained in the graph, the form of the graph and how good you are at reading and interpreting that information.
The answer depends on what information you have.
The slope of a graph provides general information about a graph. It tells you how much the y value of the graph increases (or decreases, if the slope is negative) for a given increase in x value. if you look at the general equation of a graph y = a x + b the value "a" represents the slope and the "b" value represents the value of y when x = 0. When the graph is not a straight line, the discussion gets more complicated, however the slope still describes changes in the value of the graph (you have to use calculus for this situation.)
