Some scientists believe that the average surface temperature of the world has been rising steadily. They have modeled the temperature by the linear function T = 0.02t + 8.75, where T is temperature in °C and t represents years since 1900.
(a) What do the slope and T-intercept represent?
The slope is _______ , which means that the average surface temperature of the planet is increasing or decreasing at a rate of ______°C per year. The T-intercept is _______ , which presents the average surface temperature in the year _______ .
(b) Use the equation to predict the average global surface temperature in 2100.
°C
