Answer:
i think it's the third one
Answer:
0
Step-by-step explanation:
Given

Required
Determine its new position
Because the ring was initially below the surface of the pool;
Its initial position is

Taking it to the surface of the pool;
It means, the ring travels a distance of:

It's final position is the summation of its initial position and distance travelled;



<em>Hence, 0 represents its new position with respect to the surface of the water</em>
Y=mx+b
M is the slope
B is the y intercept
In this case 4 is the slope and -9 is the y intercept
