Question

PLEASE HELP ME WITH THIS PROBLEM!!!

Answer 1

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.

Answer 2

whats the answer?

Answer 3

idk im tryin to figure it out

Answer 4

help please?

Answer 5

ok... if I write the equation

y = 0.2x + 15

can you identify the slope and y-intercept..?
