Question

Find the equation of the line perpendicular to 3x + 4y + 1= 0 and passing through (1, 1).

Solution

Correct option is

4x – 3y – 1 = 0

Equation of line perpendicular to 3x + 4y + 1 = 0 can be taken as

4x – 3y + k = 0.  

(i) Interchange coefficient of x and y

(ii) Reverse the sign between x and y  

Now, the line passes through (1, 1):

  

Hence required equation is:     

                 4x – 3y – 1 = 0.
