Chapter 1.2, Problem 10E

(a)

To determine

**To explain:** The slope and *T*-intercept.

Expert Solution

Slope represents the rate of change of temperature in the surface area of the earth.

*T*-intercept represents the surface temperature of the earth during 1900.

**Given:**

The surface temperature of the earth is a linear function,
*T* is temperature in
*t* represents years.

**Observation:**

In the linear function
*T*-intercept is 8.50.

The slope 0.02 represents the increase in the average surface temperature of the earth with a rate of

The *T*-intercept

(b)

To determine

**To predict:** The average global surface temperature in 2100 by using the equation.

Expert Solution

The average surface temperature of the earth in 2100 is predicted to

**Given:**

The surface temperature of the earth is a linear function,
*T* is temperature in
*t* represents years.

**Calculation:**

Substitute 200 for t in

The average global surface temperature in 2100 is
