A given line L has an equation 3x+4y=5. Which of the following is the equation of line which is perpendicular to the above line?  Choose the correct choice.
A) 4x - 3y = 5 B) 3x + 4y = 10 C) 3x + 5y = 5 D) 3x + 5y = 3 E) 3x – 4y = 5
For lines to be perpendicular ,   slope of line 1 * slope of line 2 = -1   (-3/4) * (x) = -1   x = (4/3)   where x is slope of line 2   4x - 3y = 5ns - 4x - 3y = 5
