OBJECTIVE: #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 is associated 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 interpret the meaning of the coefficient of x and the y-intercept of a graph of y=mx+b ACTIVITIES: In the partner pairs from Friday, so the followup exercise to problem 2.3 Then do Problem 2.4 on page 21 NOTES: HOMEWORK: P27+ 10-11

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.
