Can a discret random variable entity take numerical values

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

Which equation is graphed here? a) y = -3x + 3 b) y = -3x - 3 c) y = -1 3 x +3 d) y = -1 3 x -3
