Some scientists believe that the average surface temperature of the world has been rising steadily. The average surface temperature can be modeled by T = 0.02t + 15.0 where T is the temperature in °C and t is years since 1950. What do the slope and Tintercept represent? (a) The slope represents the increase in the average surface temperature in °C per year, and the Tintercept is the average surface temperature in 1950, or 15°C. (b) The slope represents the decrease in the average surface temperature in °C per year, and the Tintercept is the average surface temperature in 1950, or 15°C. (c) The slope represents the average surface temperature in °C per year, and the Tintercept is the increase in surface temperature in 1950, or 15°C. (d) The slope represents the average surface temperature in °C per year, and the Tintercept is the decrease in surface temperature in 1950, or 15°C. (e) The slope represents the change in the average surface temperature in °C per year, and the Tintercept is the predicted surface temperature in year 2015.

ok... if I write the equation y = 0.2x + 15 can you identify the slope and yintercept..?

Try to do the math yourself. For the first question, break it down. What does the Tintercept represent with the given problem?

so in your line you have T = 0.02t + 15 so whats the slope and T intercept..?
