The pressure of a certain gas in atmospheres, p, and its corresponding volume in liters, v, are shown in the table. A two column table with 6 rows. The first row, v, has the entries, 1, 2, 3, 4, 5. The second column, p, has the entries, 3.00, 1.50, 1.00, 0.75, 0.60. For the points in the table, does pressure vary directly with volume? If so, identify k and write an equation. No, this is not a direct variation. Yes, this is a direct variation with k = . Yes, this is a direct variation with k = 1. Yes, this is a direct variation with k = 3.
