    Answer:

    ‘k’ = 8

    Step-by-step explanation:

    P(f)= x-2y+k

    Then (-2,3) is a solution of P(f)

    ⇒ x= -2, y= 3

    We should get zero if we substitute the value of x and y in p(f)

    p(f)= (-2) -2(3) +k =0

       ⇒ -2 -6 +k =0

       ⇒ -8 +k =0

       ⇒ k = 8

    ∴ the value of ‘k’ is 8
