Answer:
The estimated average temperature for 7 month is 20 °F.
Step-by-step explanation:
The given graph shows the relation between number of months and average temperature.
The equation for the line of best fit is
Where, x is number of months and y is average temperature(°F).
We need to find the average temperature for 7 month.
Substitute x=7 in the given equation of best fit line.
Therefore the estimated average temperature for 7 month is 20 °F.
