I need some help with this

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.

What is the ratio of the length of an object in yards to the length of the same object in miles?

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
