Sorry, your wrong answer is wrong. When you move a number from one side of (equal to) to the other side, it’s sign changes. Here, you didn’t change the sign of 1.
sorry its my fault
thanks for correcting me

x = 1, y = 2
Polynomial : x - 2y + k = 0
Substituting the values of x and y, we get
1 - 2(2) + k = 0
1 - 4 + k = 0
-3 + k = 0
k = 3
