PLEASE HELP ME WITH THIS PROBLEM!!!
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 T-intercept represent? (a) The slope represents the increase in the average surface temperature in °C per year, and the T-intercept 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 T-intercept is the average surface temperature in 1950, or 15°C. (c) The slope represents the average surface temperature in °C per year, and the T-intercept 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 T-intercept 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 T-intercept is the predicted surface temperature in year 2015.
idk im tryin to figure it out
ok... if I write the equation y = 0.2x + 15 can you identify the slope and y-intercept..?
|dw:1348708493248:dw|
(b) Use the equation to predict the average global surface temperature in 2070. (Round your answer to the nearest degree.)
Try to do the math yourself. For the first question, break it down. What does the T-intercept represent with the given problem?
0.2 is the slope (0,15) is the y-int
the graph looks like |dw:1348708353492:dw|
so in your line you have T = 0.02t + 15 so whats the slope and T intercept..?
so looking at the line... is it increasing or decreasing.
Here is a better graph picture for you. Sorry I didn't help earlier.
the slope is increasing...
and T is the initial temperature when t = 0
I know the answer but I would like you to answer it yourself.
Should i give a hint or not?
i know the answer is A
(b) Use the equation to predict the average global surface temperature in 2070. (Round your answer to the nearest degree.)
