A given line L has an equation 3x+4y=5. Which of the following is the equation of line which is parallel to the above line? Pick one:
A) 4x + 3y = 5 B) 3x + 4y = 10 C) 3x + 5y = 5 D) 3x + 5y = 3 E) 3x – 4y = 5
3x+4y=5 --- equation 1   2 lines are parallel if   a1/a2 = b1/b2 ≠ c1/c2   Comparing the original line with option 3x + 4y = 10   3x+4y = 10 -- equation 2   From equations 1 and 2 , we get   5=10   which is not possible   Hence our answer is 3x + 4y = 10   Answer 3x + 4y = 10
