Step 1 :The polar coordinates are given as $(-5, \pi)$. The conversion from polar coordinates $(r, \theta)$ to rectangular coordinates $(x, y)$ is given by the formulas $x = r \cos(\theta)$ and $y = r \sin(\theta)$. We can use these formulas to find the rectangular coordinates.
Step 2 :Let's substitute the given values into the formulas. We have $r = -5$ and $\theta = \pi$.
Step 3 :Calculating $x$ gives us $x = -5 \cos(\pi) = 5$.
Step 4 :Calculating $y$ gives us $y = -5 \sin(\pi) = 0$.
Step 5 :So, the rectangular coordinates are $(5, 0)$.
Step 6 :Final Answer: The rectangular coordinates of the point are \(\boxed{(5, 0)}\).
