Suppose you are going on a geocaching adventure to find a cache that your friend has
hidden. Your friend has provided you with some clues that will help you discover what the
cache contains and where it might be. Follow the directions in each clue description below.
Clue #1:
A. The theme of the cache is "Superheroes." Carefully graph the four lines with the
following equations on the coordinate plane below to see the shape of the item. y 2 x 13 B. 2 x y 17 1
x 13
2
14
D. x 2y
C. y © K12 Inc. Clue #2: The item in the cache is thin, and you can fold it or bend it. Just like the lines you
graphed intersect at four corners, the item also has four corners. The coordinates
of the cache location correspond to one of the points where the four lines
intersect. Identify the coordinates of the points where each pair of lines intersect.
Write your answers as ordered pairs in (x, y) form.
14 :
A. Intersection of y 2 x 13 and x 2y 1
x 13 :
2
14 :
C. Intersection of 2 x y 17 and x 2y
B. Intersection of y 2 x 13 and y D. Intersection of 2 x y Clue #3: 17 and y 1
x 13 :
2 The item in the cache has several pages and has the same shape as the
geometric shape created by the intersecting lines. What is the shape of the item?
Based on all the clues, what do you think the item is? Think about this! What item(s) would you place in a cache and where might you hide it? Write
1-2 sentences in the space below to describe your geocaching idea.
