Use the plot of the point $\left(x_{0}, y_{0}\right)$ in the figure. Match the transformation of the point with the correct plot. Explain your reasoning. [The plots are labeled (i), (ii), (iii), and (iv).]
(a) $\left(x_{0}, y_{0}\right)$
(b) $\left(-2 x_{0}, y_{0}\right)$
(c) $\left(x_{0}, \frac{1}{2} y_{0}\right)$
(d) $\left(-x_{0},-y_{0}\right)$
