1. WUHSD Geometry 2015-2016 Cell Phone Tower Performance Task Pre-Performance Activity 1)Equations from Coordinate Geometry 2) Task-Specific Vocabulary

2. 1) Equations from Coordinate Geometry Equation of a line: slope-intercept form: Slope formula: Length Formula: Equation of a circle: 2 2 1 1 2 211

3. AA) FIND THE SLOPE OF A LINE THROUGH THE 2 POINTS m = 4/3 BB) FIND THE EQUATION OF THE LINE THROUGH THE 2 POINTS y = 4/3 x + 2/3 CC) FIND THE LENGTH BETWEEN THE 2 POINTS length = 5 D) WRITE THE EQUATION FOR CIRCLE A (r=5) & GRAPH IT. C = (1, 2)r = 5 ( x – 1 ) 2 + ( y – 2 ) 2 = 25 E) WRITE THE EQUATION FOR CIRCLE B (r=5) & GRAPH IT. C = (4, 6)r = 5 ( x – 4 ) 2 + ( y – 6 ) 2 = 25 FOR THE GRAPH BELOW:

4. 2) Task-Specific Vocabulary Telecommunications Engineer A person who designs and/or installs equipment for transmitting data across wired and/or cellular networks Constraint A limitation imposed by external circumstances Cell Phone Tower Dead Zone a) An area in which zombies rule b) An area which gets no cell phone reception
