20 ! 1. which linear equation has a slope of 3 and a y-intercept of –2? y = 3x + 2 y = 3x – 2 y = –2x + 3 y = –2x – 3 2.adriana writes the equation y = 2x + 4 to represent a line on a graph. henry writes an equation that has a y-intercept that is 1 unit lower on the graph but has the same slope as adriana’s line. which is henry’s equation? y = x + 4 y = 3x + 4 y = 2x + 3 y = 2x + 5

Four airplanes carrying a total of 400 passengersarrive at the detroit airport. the airplanes carry, respectively,50, 80, 110, and 160 passengers.a) one of the 400 passengers is selected uniformly at random.let x denote the number of passengers that were on theairplane carrying the randomly selected passenger. find var(x)for x as given in the problemb) one of the 4 airplane drivers is also selected uniformly atrandom. let y denote the number of passengers on the chosen driver’s airplane. find var(y) for y as given in the problem
