Big Understanding: Observation and description of changes in the world around us are the first steps in finding and learning about patterns. Essential Question: How can I make a table with a graphing calculator? 5.2 Making Tables on a Calculator Class Notes: How to make a table with a graphing calculator. 1. Press the **Y=** button or the Plot button on the upper left corner below the screen. 2. Insert your data. 3. Press the blue or yellow **2nd** button. 4. Press the **Table** button. (This button is the **Graph** button but if the calculator is on **2nd** it becomes the **Table** button) 5. You have a **Table** of your data.

//** Problem 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.**// //**3.Use your table to find y is x=5.**// If x was five, y would be fifteen. Because you would have to multiply five by three and five multiplied by three equals fifteen. (5x3=15)
 * ~ X ||~ Y ||
 * || 0 ||
 * 1 || 3 ||
 * 2 || 6 ||
 * 3 || 9 ||
 * 4 || 12 ||
 * 5 || 15 ||
 * 6 || 18 ||

//**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.**// //**3.Use your table to find y if x=5.**// If x was five, y would be fifteen. Because you would have to multiply five by one half and add two so (five multiplied by one half equals two point five, two point five plus two equals four point five) (5x0.5+2=4.5)
 * //Problem B- //**
 * ~ X ||~ Y ||
 * 0 || 2 ||
 * 1 || 2.5 ||

 * 3 || 3.5 ||

//**1.Use your calculator to make a graph for the equation y=3x. Describe the graph**// The graph is one straight line that matches up with coordinate pairs following the rule of **y=3x**. The line matches up with coordinates like (0,0) (1,3) (2,6) and so on Basically the graph is the table converted. //**2.Use your calculator to make a graph for the equation y=0.5x+2. Describe the graph.**// The graph is one straight line that matches up with coordinate pairs following the rule of **y=0.5x+2**. The line matches up with coordinates like (0,2) (1,2.5) (2,3) and so on Basically the graph is the table converted. //**3.How do the graphs for questions 1 and 2 compare?**// The graphs are different because they have different coordinates, patterns or data. //**4.How would you make a graph for the equations y=3x and y=0.5x+2 without a graphing calculator?**// By marking the coordinates on a grid and connecting the coordinates with lines to finish the graph.
