Take one of the 'x's in the table.
Write it in place of 'x' in one of the choices.
See if it produces the 'y' in the same choice.
It will only do that in one of the choices.
This is exactly how you check your solution to an equation
to see whether it works.
Answer:
This problem is easier than it appears to be at first glance! If we assume the ground is located at y = 0, then we only use the following equation to solve:
y = -9t + 18
0 = -9t + 18
-18 = -9t
t = 2
Therefore, it takes 2 units of time (whatever units the problem specifically states) for the rocket to hit the ground.
