If the straight lines x - 2y=0 and kx + y=1 intersectsat the point (1,1/2) then what is the value of k?A. 1B. 2C. `1//2`D. `-1//2`

Answer» Correct Answer - C
Since. The straight lines `x-2y=0` and `kx+y=1` intersect at the point `(1, 1/2)`
`:.` The point `(1, 1/2)` satisfies the equation `kx+y=1`
`:.` Put `x=1`, and `y=1/2` in `eq^(n) kx+y=1`,
we get `k.1+1/2 = 1 implies k=1/2`
