Pllzzz ! i've been trying to figure this out forever..

Pranza plotted point a in the coordinate plane below.

The amount spent on food and drink by 20 customers is shown below what is the modal amount spent ?

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
