Answer

Final Answer: The rectangular coordinates of the point are $(5, 0)$ .

Steps

Step 1 ：The polar coordinates are given as $(- 5, π)$ . The conversion from polar coordinates $(r, θ)$ to rectangular coordinates $(x, y)$ is given by the formulas $x = r \cos (θ)$ and $y = r \sin (θ)$ . 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 $θ = π$ .

Step 3 ：Calculating $x$ gives us $x = - 5 \cos (π) = 5$ .

Step 4 ：Calculating $y$ gives us $y = - 5 \sin (π) = 0$ .

Step 5 ：So, the rectangular coordinates are $(5, 0)$ .

Step 6 ：Final Answer: The rectangular coordinates of the point are $(5, 0)$ .
