If the co-ordinates of the middle point of the portion of a line intercepted between coordinate axes is (3, 2), then the equation of the line will be
Options:
A .  2x + 3y = 12
B .  3x+2y=12
C .  4x - 3y = 6
D .  5x - 2y = 10
Answer: Option A : A Using midpoint formula we get the coordinates of the points A and B as (6, 0) and (0, 4) respectively. Therefore, using intercept form of the striaght line, the equation of line AB is x6+y4=1 ⇒2x+3y=12
