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

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.
- 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...
- Next we can substitute a 2 for x. That gives y = (3*2)-2 which equals 4.
- Continue until you have 4 or 5 values for your data table and then make your x-y coordinate plot.
