-- 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.
Connect the two points.
You find the average rate of change of the function. That gives you the derivative on different points of the graph.
-- take the difference between the 'x' values of the two points; square it -- take the difference between the 'y' vales of the two points; square it -- add the two squares together -- take the square root of the sum The result is the distance between the two points.
A graph is more informative than an equation because a graph is easier to interpret visually, and find all the points and line them up, rather than just a slope which shows no points(data).

because when you put them together you get a graph and the points on the graph are your answer
The slope is the change in distance between any two points divided by the change in time between them.
Connect the two points.
They are all the points where the graph crosses (or touches) the x-axis.

A linear function is called "linear" because it represents a straight line. To graph a linear function, find two points that satisify that function, plot them, and then draw a straight line between them.
We set the denominator to zero to find the singularities: points where the graph is undefined.
Select a set of x values and find the value of y or f(x) - depending on how the parabola is defined. These are the values that you need to graph.
