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 = 0.01t + 8.5, 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 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 2050. °c

A.

The slope is positive and means the temperature is increasing since year 1900

T interception is 8,5 and it is the temperature in the year 1900

B. 29°C

Step-by-step explanation:

The function is the kind y=mx+b then we can see the "b" represents the value of "y" with the horizontal line in the graph, it means when x=0

the m is the slope and for our function is 0,01 and it is a positive number, in a graph a positive slope represents a line always increasing.

For the b

We just have to substitute the t with the value 2050 in the funtion

T=0,01(2050)+8,5

The result is 29°C

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
