Hannah weighed 7.2 pounds at birth. Her weight was recorded at each of her infant doctor visits. The records from her appointments from birth to six months are shown in the table below. 1. Find the line of best fit: 2. Estimate Hannah's weight at her one-year visit:​

So If Hannah weighed 7.2 lb at birth during the six months that are shown on the table hanna puts on 8.7 during those six months so if we’re estimating what her weight will be at her one year visit

8.7(what she put on during the six months)+ 15.9 (her weight now)= 24.6

I estimate she will weigh 24.6lb at her one year visit

Hope this helps
