Question

what is the meaning of the point marked on the graph? after 2 minutes, there are 4 gallons of water left in the tub. after 2 minutes, 4 gallons of water have drained from the tub. after 2 minutes, there are 40 gallons of water left in the tub. after 2 minutes, 40 gallons of water have drained from the tub.

Explanation:

The graph has the x - axis as minutes and the y - axis as gallons (of water in the tub). The marked point has an x - coordinate of 2 (2 minutes) and a y - coordinate of 40 (40 gallons). So this point represents the amount of water left in the tub after 2 minutes. We check each option:

• Option 1: Says 4 gallons left, which is wrong as y - value is 40.
• Option 2: Says 4 gallons drained, but initial amount is 60 gallons, 60 - 40 = 20 gallons drained, so wrong.
• Option 3: Says 40 gallons left after 2 minutes, which matches the coordinates (x = 2, y = 40).
• Option 4: Says 40 gallons drained, but 60 - 40 = 20 gallons drained, so wrong.

Answer:

C. After 2 minutes, there are 40 gallons of water left in the tub. (assuming the options are labeled A, B, C, D in the order given, with the third option being C)
