Select all of the pieces of information that would tell you x and y have a proportional relationship. Let y represent the distance between a rock and a turtle's current position in meters and x represent the number of minutes the turtle has been moving.

• y = 3x
• After 4 minutes, the turtle has walked 12 feet away from the rock.
• The turtle walks for a bit, then stops for a minute before walking again.
• The turtle walks away from the rock at a constant rate.
