Question

find the value of k if line 2x+ky=6 passes through point (1,2)

Answer 1

since it is given that point {1,2} passes through point 2x+ky=6,

so the point must satisfy the given equation,

hence,  x=1, y=2

putting in equation for k,

                    2x+ky=6

                   2×1+k×2=6

                     2+2k=6

                       2k=4

                       k=2

so the value of k is 2

Answer 2

Answer:

Step-by-step explanation:

2 x + k y =6 , x=1 & y=2 so , 2*1+k*2=6 , 2+2k=6 , 2k=4 , k= 2
