A scientist measured the water pressure at different depths. She made a table showing her findings. The x-values represent the depth, in meters. The y-values represent the pressure in atmospheres (atm). xy00153306Assuming there is a proportional relationship, which additional set of values could be included in the table?

The table shows that pressure is proportional to depth: at 15 meters, pressure is 3 atm, so the rate is 3 ÷ 15 = 0.2 atm per meter. At 30 meters, the pressure is 6 atm, confirming that rate. At 10 meters, the pressure would be 10 × 0.2 = 2 atm, so the additional values could be (10, 2), choice A.
