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

$y=-13x+111$

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.

$y=-13(7)+111$

$y=-91+111$

$y=20$

Therefore the estimated average temperature for 7 month is 20 °F.

Substitute x to be 7 (for month 7) and work out the equation:

y = -13(7) + 111

y = -91 + 111

y = 20

Your answer is 20 degrees Fahrenheit.
