Answer 1

Since the number of gallons of water in the pool increases by 2 every minute, the x-value represents the number of minutes it will take to fill the pool to 24 gallons.

Since there is 2 gallons of water in the pool after 1 minute, the x-value would be 1.

Therefore, the x-value of the point (x, 24) is 1.

So the correct answer is B) 12.
