Point R is at (4, 1.5) and Point T is at (4, 2.9) on a coordinate grid. The distance between the two points is . (Input numbers and decimal point only, such as 8.2.)

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
