sir i don't know how to show that the =n lx+my=1(l &m is not=0) represents a straight line.
 
Use the definition of the Standard Form for the equation of a line.

A*x + B*y = C, where A, B, C are Real numbers such that A and B are not both zero.

A = l

B = m

C = 1

If you don't like that definition, solve the equation for y, and use the definition for the Slope-Intercept form.

There are at least three other definitions for straight lines that we could use.
