A
____________________
function
is
any
function
that
graphs
to
a
straight
line
.
What
this
means
mathematically
is
that
a
linear
function
has
either
one
or
two
variables
with
no
exponents
or
____________________
.
The
equation
of
a
straigh
line
is
usually
written
this
way
y
=
____________________
+
b
.
A
line
with
a
____________________
slope
rises
from
left
to
right
whereas
a
line
with
a
____________________
slope
falls
from
left
to
right
.
If
two
lines
have
the
same
slope
the
lines
are
said
to
be
____________________
.
However
,
if
they
have
negative
reciprocal
slope
the
lines
are
called
____________________
.
You
can
____________________
the
graph
of
a
linear
function
using
just
two
____________________
.
If
you
are
unsure
you
can
use
more
points
to
double
