Someone asked you for driving directions for the shortest route from the stadium to the art museum. What directions would you give them using the graph as a map?
East 8 blocks, south 2 blocks (or 8 to the right and 2 down)
What is the length of the hypotenuse?

Is this a function?
[[x,y],[8,4],[10,5],[12,6],[10,5]]
Yes! Even though 10 is used twice it has the same output both times
What is the rate at which the line is rising?

When an image is mirrored across the x or y axis
Pretend you own a helicopter. Is it always a shorter distance to fly rather than drive? You must explain why you think you are correct to get the points.
No, if you can drive without turning the distances are the same. It is only shorter to fly when the car has to turn.
What is the length of the hypotenuse?

y=2x
Mr. Jones drew hallways in his floor plans for a new school that he thinks are parallel and a hallway that connects them. How can he prove they are parallel using angles?
Angles created by the connecting hallway and one parallel line will be equal to angles created by the connecting hallway and the other parallel line.
(Angles are congruent)
