Answer 1

Let x = the number of hours since 5 a.m.

Let y = temperature, °F

Let the total temperature change be modeled by the expression

y = ax + b

At 5 a.m., x = 0 and y = -9.4°F. Therefore

b = -9.4

When x = 6 hours, y = 2.8°F. Therefore

6a + b = 2.8

6a - 9.4 = 2.8

6a = 12.2

a = 2.0333

The expression is

y = 2.0333x - 9.4

Answer:

y = 2.0333x - 9.4

where

x = hours since 5 a.m.

y = temperature, °F
