A baby weighs 7 pounds of birth. The table shows the babies weight after each month of its birth up to the sixth month.

Month | weight (Pounds)
0 | 7
1 | 8
2 | 9
3 | 10
4 | 11
5 | 12
6 | 13
what would be the rise/run

The rise would be the difference in weight between the final month and the initial month, which is 13 - 7 = 6 pounds.

The run would be the difference in months between the final month and the initial month, which is 6 - 0 = 6 months.

Therefore, the rise/run would be 6/6 = 1.

This means that on average, the baby is gaining 1 pound per month.
