Answer #1:
The y intercept should be zero because of Newton's second law. Force and
acceleration are directly proportional. The X intercept indicates that there is
some force required to overcome friction if friction is not negligible. This value
is the force required to accelerate the object usually very small.
===============================
Answer #2:
It's even easier than that. The graph had better pass through the origin,
because zero force on an object means it can't be accelerating, and zero
acceleration of an object means there can't be any net force acting on it.
Go back and read Answer #1 above very carefully. It correctly says that the
y-intercept is zero. But doesn't that mean that the graph must go through the
origin, and that the x-intercept is therefore also zero ? I'm just sayin . . .
It is the work done or the energy utilised
Distance-time graph will show a straight line with a positive slope. Speed-time graph will show a horizontal line at the uniform speed. Acceleration-time graph will show a horizontal line at a = 0.
a line graph
Yes, every tree ia a bipartite graph (just see wikipedia).
A Hamiltonian path in a graph is a path that visits every vertex exactly once. It does not need to visit every edge, only every vertex. If a Hamiltonian path exists in a graph, the graph is called a Hamiltonian graph.
No, in general, the force vs acceleration graph does not always pass through the origin. This is because there may be a non-zero force acting on an object even when it is at rest. The presence of a non-zero force at rest would lead to a non-zero intercept on the force vs acceleration graph.
Usually time but it could depend on the specific graph.

The answer will depend on the variables plotted on the graph!
Acceleration is directly proportional to applied force. When acceleration increases, force also increases. If the force is tripled, the acceleration will also be tripled. Note that the mass must remain constant...
It is not, if it is a graph of force against acceleration.
The slope of a velocity-time graph represents acceleration.
You might assume that acceleration is proportional to force - specifically, using Newton's Second Law. However, you would need to know the mass on which the force acts - otherwise, you simply don't have enough information.
change in velocity
That the force that causes the acceleration is not constant.
The slope of a velocity-time graph represents acceleration.
Magnitude of acceleration (but conveys no informationregarding acceleration's direction).
