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=0.02t + 8.45, where T is temperature in C and t represents years since 1900.

Missing Part:

What do the slope and T-intercept represent?

The slope is 0.02 and the t intercept is 8.45

Step-by-step explanation:

Given

Required

Determine the slope and the t-intercept

The general form of a function is;

Where m represents the slope and b, the intercept;

By comparing directly to

Hence;

The slope is 0.02 and the t intercept is 8.45

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
