85001 rounded to the nearest ten thousand is 90,000. Because there is a 5 in the thousands place, the 8 in the ten thousands place rounds up to 9. Always use the numeral to the right of the place value you are rounding. If it is 5 or greater the number increases. If it is less than 5, it remains the same.
Let y be the temperature
Let m be the rate of temperature drop in degrees per hour
Let x be the number of hours elapsed since 8PM
The initial temperature (at x = 0) is 0
y = mx
Four hours from 8 PM, the temperature was -16.8 degrees
-16.8 = m(4)
m = -4.2 degrees per hour
At 9PM, one hour will have elapsed.
y = -4.2(1)
y = -4.2 degrees
