The y-intercept is the starting position at earth's surface. the coordinates of the y-
intercept are (o, temperature at earth's surface).
3. what is the b-value of the y-intercept for your equation? (1 point)

The b-value of the y-intercept for the equation is b=3

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem

The y-intercept is the point (0,3) ----> given problem

so

The x-coordinate of the y-intercept is 0

The y-coordinate of the y-intercept is 3

therefore

The b-value of the y-intercept for the equation is b=3
