Which lines are perpendicular to the line y – 1 = 1/3(x+2)? Check all that apply.

Please explain why, I would appreciate it

-y + 2 = –3(x – 4)

-y − 5 = 3(x + 11)

-y = -3x – 5/3

-y = 1/3x – 2

-3x + y = 7

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b.you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c.you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d.you spend $5 plus $10 per week until you have less than $45.
