Graph :
\(1) Draw the coordinate plane.
\(2) Graph the equations
and
for
.
Indicate the obtained points on the graph.
\Based on the values of
, indicate the direction of
as it increases with an arrow.
(b)
\Solve for the value of
:

.
Substiute the value
in
.
.
.
The value of
lies over the interval
.
.
Since
we have
.
Since
we have
.
Therefore, the cartesian equation is
, where
