I think the coordinates are 1, 10 but not positive because if you graph it you can see a kite in it so make the point close to 4,10
The area of the entire sector is 
The area of the triangle OAB is
.
So, the area of the segment is 
The temperature at 9 am was -11 degrees.
We know that at 5 am, it was -7 degrees. Since the change of temperature is a negative number, then we subtract the absolute value of the change from -7. -7 - 3 = -10. Following this pattern, we then have:
-10 - 2 = -12 (6 am - 7 am)
-12 - 5 = -17 (7 am - 8 am)
-17 + 6 = -11 (8 am - 9 am, added since it was a positive change of temperature)
And our final answer is -11 degrees Fahrenheit.
