Functions
Goals of today
• Graph points
• Coordinate plane
• How do graphs tell a story
Drawing the C.P.a) Use a Rulerb) Label Axisc) Set scaled) Label Points
Points in the coordinate plane are indicated with ordered pairs (x,y)
Examples:
(4, 5)
(-2, 3)
(-3, -4)
(3, -6)
(0, 0)
Think: (↔, ↕)
The coordinate plane
Points in the coordinate plane are indicated with ordered pairs (x,y)
Examples:
(4, 5)
(-2, 3)
(-3, -4)
(3, -6)
(4,5)
(-2,3)
(-3, -4)
(3, -6)
The Four Quadrants
I
x

(+,+)(-,+)
(-,-) (+,-)
Graphing Stories
• Stairs One• Stairs two• Running• Distance from Home
Will probably just do two of them
Now let’s just talk not write
• Tell the story of each graph

Summary
• Positive Change(“increasing”)
• Negative change (“decreasing”)
• Zero Change
• Undefined Change
