# For specifying a straight line, how many geometrical parameters should be known?

A. 1

B. 2

C. 4

D. 3

Answer :

Different form of equation of straight line are

**Intercept form:**

where, a and b are the intercepts on the axis

In intercept form, we need two parameters ‘a’ and ‘b’ to specify a straight line

**Slope – Intercept Form:**

y = mx + c

where m = tan θ, and θ is the angle made with positive x – axis

and c is the intercept on y – axis.

So, we need two parameters ‘m’ and ‘c’ to specify a straight line.

Hence, the correct option is **(b)**
