please answer seriously.​

Answer 1

Answer:

-3

Step-by-step explanation:

x= 5

y= k

Substituting the values of X and y in the equation,

2×5 + k - 7 = 0

10 + k = 7

k = 7 - 10 = -3

Answer 2

Answer:

substitute given point in that equation,

=> 2*5 + k -7 = 0,

=> 10 + k -7 = 0,

=> k + 3 = 0,

=> k = -3.
