Question

Q11) Find the value of k if (-2, 3) is a solution of x - 2y + k = 0 *

Answer 1

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
