How to create a data table and make a coordinate graph from an equation.

Suppose we have an equation like:

y=3x-2

To make a graph from this (or a similar equation) we do the following:

• Determine the variables - in this case x and y.
• Make table with two columns labelled x and y.
  

  x	y

  
  
• Now you must decide which variable you wish to substitute first - x or y.
  Let's do x=1. Substituting 1 in place of x gives us y=(3*1) -2, which is 1. Now we put the value in the table and pick another...

  x	y
  1	1

  
  
• Next we can substitute a 2 for x. That gives y = (3*2)-2 which equals 4.
  

  x	y
  1	1
  2	4

  
  
• Continue until you have 4 or 5 values for your data table and then make your x-y coordinate plot.

OBJECTIVE: #To connect solutions in graphs and tables to solutions of equations. #To find a solution common to two linear equatons by graphing. # to understand how the y-intercept appears in tables and equations. #to understand how the rate of change (the coefficient m) appears in equations and affects the graph of a line. ACTIVITIES: Page 39 Problem 3.2 Do the following: 1)Using the computer graphing program, plot the 5 equations on a single graph using a full sheet of paper. Label them. 2) By hand - make a data table for the values -3 to +3 for each equation and plot them on a differnet graph (same size as 1). Answer questions A, D and follow-up 1 and 2 NOTES: HOMEWORK: P51 28 and 29a [ On-Line Plotter] [ Make your data table!]
