Toeing the Line
Do you always toe the line?
OBJECTIVE: To learn how to graph a line using a table of values
In this lesson, you'll learn how to graph a line by constructing a table of values. At the top of the applet below is a list of numbers. Drag the numbers to fill up all the boxes. Click "Check" when done. If your numbers are correct, the applet will confirm that the graph is "Linear!"; otherwise, it will display the words "Not linear!" Keep track of the number of lines that you form. Then answer the questions that follow.
QUESTION: How many distinct lines can you form by filling up all the boxes using the numbers listed?
QUESTION: How many ways are there to fill up all the boxes to form the same line?
TODAY you learned how to graph a line by coming up with a table of values and plotting the points.
In a future lesson, you will learn how to graph a line without using a table of values. We hope you ENJOYED today's lesson.
