Q point is also called operating point.Q point is mainly adjusted in transistors to make it stable. i.e., to operate the transistor in safe mode. Depending up on the operating current and voltage Q point is adjusted. The Q point defines the operating condition of the transistor and the transistors which quiescent point is adjusted are denoted as Q1,Q2.........Qn
Q
depending on the graph where point Q was you would not be able to tell where point Q ended after the rotaion finshed
The operating point of a transistor is called the Q point because Q stands for "quiescent," which means a state of rest or inactivity. It represents the DC bias conditions at which the transistor operates when there is no input signal. This point is crucial for analyzing the transistor's behavior and ensuring proper amplification.
selection of q-point is necessary in amplifiers,because if the q-point is not in the middle of load line the output may be clipped i.e not in the power supply range.
If (p, q) is any point on the line, then the point slope equation is: (y - q)/(x - p) = 2 or (y - q) = 2*(x - p)

Point S
Q point which is quiscent (silent) point is the operating point of a transistor where the variations of collector current and collector-emitter voltage take place when signal is applied.
The point with coordinates (p, q) will be rotated to the point with coordinates [(p - q)/sqrt(2), (p + q)/sqrt(2)].
.
the fixed amount of current and voltages are developed across the transistor is called biasing. thus the fixed voltages and current developed are called Q-point
Q value is the quality check point in dissolution testing
