Question

If (2,-3) lies on the line of equation 4x+2y+k=0 then find the value of k

Answer 1

Answer:

x=2

y=-3

4x+2y+k=0

4×2+2×(-3)+k=0

8-6+k=0

2+k=0

k=-2

The value of k is -2.

Answer 2

HEY THERE,HERE IS YOUR ANSWER:

Answer:

4x+2y+k=0

as x=2 and y=-3 ( given in the question) (2,-3)

4*2+2*-3+k=0

8-6+k=0

2+k=0

k=-2

We got -2 because when we put 2 on the other side of the equation it changes into -2.
