Help
Background: Ms. Smith was expecting to get her new iPad in the mail when she got home from work. She had been telling everyone how excited she was to get the newest version. Shockingly, someone broke into her mailbox and stole it. She talked to all the people who had been at her house that day and each said they had not seen anything and that the mailbox was in good condition when they left. She determined that the last person to leave her house was likely the culprit. The diagram below shows the “footprints” left in front of the mailbox. Who was it?
Clues:
The Neighbor walks to work
The Handyman rides a bike
The Cook rides a motorcycle
The Maid drives a car
The Nephew has a dog

Neighbour

Explanation: Taken perspective from the given clues:

The Neighbor walks to work 

The Handyman rides a bike 

The Cook rides a motorcycle 

The Maid drives a car 

The Nephew has a dog

If we assume that the handyman delivered the iPad in the mailbox, then

The direction of the cook, Nephew and his dog are perpendicular to the direction of the bike of the handyman. So, it can't be the cook, Nephew and the maid.

The two suspects are the handyman and the neighbour.

If the handyman actually dropped the iPad and left, then, the neighbour should be the culprit.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
