For specifying a straight line, how many geomatrical parameters should

1.	For specifying a straight line, how many geomatrical parameters should be known ?A. 1B. 2C. 4D. 3
Answer» Correct Answer - B Equation of straight lines are `y=mx+ c`, Parameter =2 .....(i) `(x)/(a)+(y)/(b)=1`,Parameter =2 .....(ii) `y-y_1=m(x-x_1)`, Parameter =2 ......(iii) and `xcosw+ysinw=p`, Parameter =2 .......(iv) it is clear that from Eqs. (i), (ii), (iii), and (iv), for specifying a straight line clearly two parameters should be known.
