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
