Answer

(a) We can see the point plotted on the graph below. (b) We can write two pairs of polar coordinates for this point: $(2, 180^{\circ})$ $(-2, 0^{\circ})$

Work Step by Step

$(-2, 0)$ (a) We can see the point plotted on the graph below. (b) $r = \sqrt{(-2)^2+(0)^2} = 2$ Since the point is on the negative x-axis, the angle $\theta = 180^{\circ}$ We can write two pairs of polar coordinates for this point: $(2, 180^{\circ})$ $(-2, 0^{\circ})$
