 * Essential Question: How can a graphing calculator help me to discover relationships between variables? **


 * Problem 5.1: Experiment with your graphing calculator and the following equations. Graph one set of equations at a time. For each set, two of the graphs will be similar in someway. and one of the graphs will be different. Answer questions A and B for each set. **


 * Set 1: y = 3x - 4 y + x squared y + 3x + 2 **
 * Set 2 :y= 5 y= 3x y= 1x **
 * Set 3: y= 2x+3 y= 2x-5 y=0.5x+2 **
 * Set 4 :y= 2x y= 2/x y= x+5 **


 * A. 1. Which two equations in the set have graphs that are similar? **


 * 2. In what ways are the two graphs similar? **


 * 3. In what ways are the equation for the two graphs similar? **


 * B. 1. Which equation in the set has a graph that is different from the graphs of the other equations? **


 * 2. In what way is the graph different from the other graphs? **


 * 3. In what way is the equation different from the other equations? **


 * Set 1: y = x squared y + 3x + 2 **


 * A.) **
 * 1. y = 3x - 4 and y + 3x + 2 **
 * 2. They are they are parallel. **
 * 3. They are similar because the both have multiplication. **
 * B.) **
 * 1. y = x squared **
 * 2.They are parallel and this one looks like it going to become an oval. **
 * 3.The others are not squared and the amount is different. **
 * Set 2:y= 5 y= 3x y= 1x **


 * A.) **
 * 1. y=3x and y=2x are similar becuase they have a sum. **


 * 2. They are similar becuase they steadily cross each other. **


 * 3. They have a sum that was very similar because y=3x and y=1x are separated by a number. **


 * B.) **
 * 1. y=5 because it crosses the graph horizontal **


 * 2 .It doesn't cross angled and its separated from the others. **


 * 3. It doesn't have a sum (x) **


 * Set 3:y= 2x+3 y= 2x-5 y=0.5x+2 **


 * A .) **
 * 1. y=2x+3 and y=2x-5 **


 * 2. they have, are crossing together. **


 * 3. they have 2x_(+ or -)# **


 * B.) **
 * 1. y=0.5x+2 **


 * 2 .It crosses a different way **


 * 3. It doesn't have 2x_ (+or /) = #. **


 * Set 4:y= 2x y= 2/x y= x+5 **


 * A.) **
 * 4: 1. y=2/x and y=x+5 **


 * 2. they do the same thing, curve. **


 * 3.they have a sum. **


 * B.) **
 * 1. y=2x **


 * 2.because it crosses **


 * 3.doesn't have a sum. **


 * Follow up: **


 * A. x=2 y=4 **


 * B.x=2/3 y=21/3 **


 * C. x=3.25 y= 6.50 **


 * d. **
 * x || ** 0 ** || ** 1 ** || ** 2 ** || ** 3 ** || ** 4 ** || ** 5 ** || ** 6 ** ||
 * ** y ** || ** 0 ** || ** 2 ** || ** 4 ** || ** 6 ** || ** 8 ** || ** 10 ** || ** 12 ** ||


 * 2. **
 * ** x ** || ** 0 ** || ** 1 ** || ** 2 ** || ** 3 ** || ** 4 ** || ** 5 ** || ** 6 ** ||
 * ** y ** || ** 3 ** || ** 5 ** || ** 7 ** || ** 9 ** || ** 11 ** || ** 13 ** || ** 15 ** ||
 * 3. They both have a number x and they both go in an stable adding **
