Step-by-step explanation:The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet " ⇒ D

Step-by-step explanation:

The boiling point of water (measured in degrees), at altitude (measured in feet), is modeled by the function T(a) = −0.0018 a + 212, where

a is the altitude measured in feet

T(a) is the boiling point of water in degree

The form of the linear function is f(x) = mx + b, where m is slope (the rate of change), and b is the y-intercept (the value of f(x) at x = 0)

By comparing between the form of the function and the given function

∴ m = -0.0018 ⇒ degrees per foot

∵ The sign of the slope is negative

∵ The slope = Δf(x)/Δx

- That means T(a) is decreasing function

∴ The boiling point is decreases when the altitude increasing

∵ -0.0018 =  degrees per feet

∴ The boiling point decreases by 18 degrees as the altitude

   increases by 10,000 feet or the boiling point decreases by 1.8

    degrees as the altitude increases by 1,000 feet

The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet "

0.4

Step-by-step explanation:

so from the line, you can see that F = -0.4

F = -0.4

-F = ?

-(F) = -(-0.4)

-(-0.4) = 0.4

-F = 0.4
