Sam wants to know how long it will take to fill his baby pool that holds 24 gallons. After 1 minute, there are 2 gallons of water in the pool. He plots the points (0,0) and (1,2) on his coordinate plane. What is the x-value of the point (x, 24)?

A 66
B 12
C 23
D 25
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.
