Section 1.3
Graphing Equations
One of the things you need to be able to do upon
completion of this course is to graph many types of
equations.
There are many methods to use.
In this
section, we’ll create a table of values and ordered
pairs, and then plot the points in the coordinate plane.
Once we have the points plotted, we can connect the
dots to get a good picture of the equation.
•
We need to be able to determine if a point that
we’re given lies on the graph of a specific
equation.
Example 1:
Determine which of the points (3, 2),
(1, 3) and (0, 2) are on the graph of the equation

When graphing an equation, it is usually very
helpful to find the
x
intercept(s)
and the
y
intercepts
of the graph.
An
x
intercept is the first coordinate of the ordered
pair of a point where the graph of the equation
crosses the
x
axis.
To find an
x
intercept, let
