Question

IF THE POINT (1,-2) LIES ON X-2Y+K FIND THE VALUE OF K

Answer 1

Answer:

Step-by-step explanation:

(1,-2) lies on x-2y+k. On satisfying (1,-2) we get. 1+2+k=0.

Hence k= -3

Answer 2

k = -5

Step-by-step explanation:

In this case, it is given that, if the points (1,-2) lies on x-2y+k=0, we need to find the value of k.

If the given points lie on given lines, the points will satisfy the equation. It means put x = 1 and y = -2 in the above equation and finding the value of k such that,

$x-2y+k=0\\\\1-2(-2)+k=0\\\\1+4+k=0\\\\k=-5$

So, the value of k is -5.
