The given equation passes through the given point,
2x-ky=9
The given equation passes through the point (-1,-1).
⇒ 2(-1) - k(-1) = 9
⇒ -2+k=9
⇒k=9+2
⇒k=11.

x = -1
y= -1
The equation is 2x - k y = 9 .This equation. passes through (-1 , -1)
we have to simply put the value in it
2 × (-1) - k × (-1) = 9
-2 + k = 9
k = 9+2 = 11
∴k = 11
y= -1
