Question

Which one is it
a
b
c
d

Answer 1

`y = 2x \\ y = 4x + 12`

Put the value of y in the bottom equation i.e y = 2x

`2x = 4x + 12 \\ 2x - 4x = 12 \\ - 2x = 12 \\ x = - 6`

Now put the value of x in equation 1

`y = 2x \\ y = 2 * ( - 6) \\ y = - 12`

Hence, Option D (-6,-12) is correct!!

Answer 2

The answer is D (-6,-12)
