What is the initial value of the function represented by this graph? a coordinate grid is shown with x- and y-axes labeled from 0 to 7 at increments of 1. a straight line joins the ordered pair 0, 3 with the ordered pair 7, 6. 0 3 6 7

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
