Answer :

Answer:

y=x+8  and y=3x

Step-by-step explanation:

The Given point is (4,12)

now we can substitute the point in each of the function and check wether it lies on it or not.

A.  y=x+8

substitute y=12,x=4

12=4+8=12 which is true

B.  y=3x

substitute y=12,x=4

12=3*4=12 which is true

C.  y=2x

substitute y=12,x=4

12=2*4=8  which is not true

D.  y=x+6

substitute y=12,x=4

12=4+6=10 . which is not true

Therefore option A and B are correct.
