OBJECTIVE: Investigation 2: #To recognize linear relationships from tables; for each unit change in one variable there is a constant rate of change in the other variable. #To determine whether a set of data is linear by examining its graph #To recognize how rate of change between two variable sis asociated with its representations #To recognize that the change in rate will change the steepness of a line and the coefficient of x(the independent variable) #To interpet the meaning of the coefficient of x and the y-intercept of a graph of y=mx+b ACTIVITIES: Students do problem 2.3. Do A independently. Join groups of three to finish B,C,D, and E. on a separate sheet. NOTES: Introduce data tables.. HOMEWORK: P30 #18

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.
