Answer
$(3,0)$
Work Step by Step
The point $(x,y)$ in the rectangular coordinate system can be expressed as:
$x=r \ \cos(\theta)$, $y=r \ \sin(\theta) ...(1)$
Here, we have $r= -3$ and $ \theta= \pi$
Plug these values in equation (1) to obtain:
$x=(-3) \cos(\pi)=(-3)(-1)=3 \\
y=(-3) \sin(\pi)=(-3)(0)=0$
Therefore, the point has coordinates $(3,0)$ in the rectangular coordinate system.
