Graphing linear equations
1.
2. Linear Equation: an equation whose
graph forms a line.
1143 =− yx

+−= xxy
is linear.
is not.
In linear equations, all variables are
taken to the first power.
Linear means of a
line. So a linear equation is the equation
of a line.
Why?
3. Suppose you were asked to graph the
solution set of the linear equation,
.3=+ yx
You could start by creating a table of
values.
