If (a,-2 a), a>0 is the midpoint of a line segment intercepted between the co-ordinate axes, then the equation of the line is
Options
- Ax-2 y+4 a=0
- B2 x-y=4 a
- Cx-2 y=5 a
- D2x-y+4 a=0
Correct answer
B. 2 x-y=4 a
Step-by-step solution
(A) Given point (a,-2 a) is the midpoint of the intercepts. Let Points A, B, M be as shown in figure. Hence the intercept points are (2 a , 0) and (0,-4 a ) Equation of line from intercept in intercept form. x 2 a + y -4 a =1 2 x-y=4 a
