horizontal
makes line steeper or flatter
A graph which consists of short straight lines which keep changing direction. Example : a graph line which is inclined at say, 30 degrees to a horizontal, then changes direction instantly to a line which is say, inclined at 60 degrees to the horizontal , etc. If the shape of a graph is not a series of straight lines joined to each other, then it is not a step graph.
Left to right
The standard expression for a straight line graph is y = ax + b
A Compound Graph Is An Extension Of a Standard Graph.
Speed (in the radial direction) = slope of the graph.
the left end of the graph is going in a positive direction and the right end is going in a negative direction.
In an undirected graph, an edge is an unordered pair of vertices. In a directed graph, an edge is an ordered pair of vertices. The ordering of the vertices implies a direction to the edge, that is that it is traversable in one direction only.
In the vertical direction.
In the vertical direction.
horizontal
makes line steeper or flatter
It gives the velocity of the object in the radial direction. The graph gives no information whtsoever about motion in a transverse direction.
In the vertical direction.
The scale varies on depending on the graph; there is no standard scale. It is whatever you want it to be.
speed does not indicate direction, so there is no negative on the graph.
