Some scientists have modeled the temperature by the linear function T = 0.02t + 8.3, where T is temperature in .C and t represents years since 1900. (a) What do the slope and T-intercept represent? .C per year. The T-intercept is J, which presents the average The slope is ,which means that the average surface temperature of the planet is [--Select--- ] at a rate of surface temperature in the year (b) Use the equation to predict the planet's average surface temperature in 2070.
