 * Big Idea: Observation and description of changes in the world around us are the first steps in finding and learning about patterns. **

5.2
 * A **
 * 1 Use your calculator to make a table for the equation y=3x **


 * 2 Copy part of the calculator’s table onto your paper **
 * X || Y ||
 * 0 || 0 ||
 * 1 || 3 ||
 * 2 || 6 ||
 * 3 || 9 ||
 * 4 || 12 ||
 * 5 || 15 ||
 * 6 || 18 ||



3 Use your table to find y if x=5 **

If x=5, y=15

 * B **
 * 1 Use your calculator to make a table for the equation y=0.5x+2 **


 * 2 Copy part of the calculator’s table onto your paper **
 * X || Y ||
 * 0 || 2 ||
 * 1 || 2.5 ||
 * 2 || 3 ||
 * 3 || 3.5 ||
 * 4 || 4 ||
 * 5 || 4.5 ||
 * 6 || 5 ||

If x=5, y=4.5
 * 3 Use your table to find y if x=5 **


 * 5.2 Follow-Up **

** The graph is diagonal and pretty steep
 * 1 Use your calculator to make a table for the equation y=3x. Describe the graph

The graph is not steep, it's closer to being flat. it starts at 2 in the third quadrant, goes through the first, ends in second The Y=3x graph is steeper than Y=0.5+2
 * 2 Use your calculator to make a graph for the equation y=0.5x+2. Describe the graph **
 * 3 How do graphs 1 and 2 compare **


 * 4 How would you make a graph for the equations y=3x and y=0.5x+2 **

I would first make a table of the information then create a graph out of it
