Anyone else failing everything and feel like dyin life is boring
also I need help on math:
Write a system of inequalities whose solution is to set of all points in quadrant I not including the axes.

Yeah so if your smart pls help
also I dunno what the "quadrant I" means​

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
