To find the relationship between the number of stitches and the length, we can look for a consistent factor or multiply.

Let's analyze the data from the table given:

  • For Length 1 cm, Stitches = 7.
  • For Length 3 cm, Stitches = 21.
  • For Length 4 cm, Stitches = 28.
  • For Length 6 cm, Stitches = 42.

Now let's check if there's a consistent multiplier:

  • 1 cm: 7 stitches (7 * 1 = 7)
  • 3 cm: 21 stitches (7 * 3 = 21)
  • 4 cm: 28 stitches (7 * 4 = 28)
  • 6 cm: 42 stitches (7 * 6 = 42)

We can see that the number of stitches is consistently 7 times the length of the row.

Therefore, the correct response would be: The number of stitches is 7 times the length.
