If the chord of the ellipse x^2 4 + y^2 9 =1 having (1,1) as its middle point is x + y= , then
Options
- A+ =1
- B+1=
- C-1=
- D2 -1=3
Correct answer
B. +1=
Step-by-step solution
x^2 4 + y^2 9 =1 Equation of chord having (1,1) as its middle point is T = S ₁ aligned & x 4 + y 9 -1= 1 4 + 1 9 -1 & 9 x+4 y=13 x+ 4 9 y= 13 9 = 4 9 , = 13 9 & - =1 +1= aligned
