For specifying a straight line, how many geometrical parameters should be known?
Solution:
Different form of equation of straight line are slope intercept form, y = mx + c, Paramerer = 2
Intercept form, $\frac{\text{x}}{\text{a}}+\frac{\text{y}}{\text{b}}=1,$ parameter = 2
One-point from, y - y1 = m(x - x1), parameter = 2
Normal form, $\text{x}\cos \text{w}+\text{y}\sin\text{w}=\text{P},$ Parameter = 2
Hence, the correct option is (b).
