The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212

 D     b = -2E +212

Step-by-step explanation:

The slope is given by -2 for every 1000 ft

The initial value is 212 degrees

We can use

y = mx+b  where m is the slope and b is the initial value

y = -2x +212

We are at an elevation of E thousand ft

Replace x with E

y = -2 *E +212

b is the boiling point at this elevation

We  replace y with b

b = -2E +212

D)

Step-by-step explanation:

To start, we know that the initial boiling point is 212 degrees F. For every 1 added to E, the boiling point decreases by 2. So, we havethe equation 212 - 2E or -2E + 212 = b or D).
