Answer :

Given: Point (4,1) , line 3x – 4y + k = 0 and length of perpendicular is 2 units


To find: The values of k


Formula used:


We know that the length of the perpendicular from (m,n) to the line ax + by + c = 0 is given by,


D



The equation of the line is 3x – 4y + k =0


Here m= 4 and n= 1 , a = 3 , b = -4 , c = k and D=2 units


D


D



. or


or
