Plz im my little brother

mr reynolds swcond grade class grew some plants every week they measured the plants to see how much they grew they used connecting cubes to measure the heights here is a table showing the plant growth complete and use the table to answer the questions and complete the equation

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
