Questions
A line through is such that it makes unequal intercepts on the axes, and the intercept between the axes is trisected at P, an equation of the line is
detailed solution
Correct option is B
Let the equation of the line be xa+yb=1,which meets x-axis at A (a, 0) and y-axis at B (0, b). Thenthe coordinates of the points which divide AB in the ratio 1 : 2 and 2 : 1 are respectively 2a3,b3 and a3,2b3 Now if 2a3,b3 represents P (1, 2) then a=3/2,b=6 and the required equation of the line is 2x3+y6=1⇒4x+y=6 which is given in (b) If a3,2b3 represents P (1, 2) then a = b = 3and the equation of the line is x + y = 3 which makes equal intercepts on the axes and so we do not consider this.Talk to our academic expert!
