You're looking at one specific velocity/time graph that we can't see.
From your description, we can tell that the object whose motion is described
by that graph is moving at a constant rate of speed ... which is exactly what
you just said while looking at the graph.
A physically impossible line segment on a velocity vs. time graph would be one with a horizontal slope, indicating constant acceleration. This would violate the laws of physics, as constant acceleration requires a non-zero force. Similarly, a vertical line segment would represent an instantaneous change in velocity, which is also physically impossible as it would require infinite acceleration.
The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.
The first law of motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force. In the case of an ice skater sliding across the ice at a constant velocity, the skater will continue moving at that constant velocity unless a force (like friction or wind resistance) acts to change their motion.
No, it is not. At a constant speed, yes. But velocity has a direction component, and by running on (following) a curve, a change of direction (and, therefore, velocity) will have to be made. Again, note that speed can stay the same, but velocity has a direction vector associated with it that cannot be ignored.
Since the car is moving with a constant velocity, the net force acting on the car is zero. This is in accordance with Newton's First Law of Motion, which states that an object in motion will stay in motion with a constant velocity unless acted upon by a net force.

Yes, velocity remains the same when both speed and direction remain constant. Velocity is a vector quantity that includes both speed and direction, so as long as both are unchanged, the velocity will remain constant.
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
a body at rest will stay at rest unless acted on by an unbalanced force; also a body in motion at constant velocity will stay in motion at constant velocity unless acted on by an unbalanced force
Objects would move with constant velocity or stay at rest.
an acceleration of Zero, and a constant Inertia.
No. If the speed varies, the body accelerates, and velocity cannot be constant.
A body is moving at constant velocity including zero at Equilibrium Condition, No change of energy or zero force. With force a body can accelerate, move with increasing velocity.
