1. **State the problem:**
Find the vector equation of a line parallel to the line given by
$$\begin{pmatrix} x \\ y \\ z \end{pmatrix} = \begin{pmatrix} 4 \\ 2 \\ -3 \end{pmatrix} + t \begin{pmatrix} -2 \\ 5 \\ 2 \end{pmatrix}$$
that passes through the point $(2,5,-3)$.
2. **Recall the formula for a vector equation of a line:**
$$\vec{r} = \vec{r_0} + t \vec{d}$$
where $\vec{r_0}$ is a point on the line and $\vec{d}$ is the direction vector.
3. **Identify the direction vector:**
The given line has direction vector
$$\vec{d} = \begin{pmatrix} -2 \\ 5 \\ 2 \end{pmatrix}$$
Since the new line is parallel, it has the same direction vector.
4. **Use the given point as $\vec{r_0}$:**
$$\vec{r_0} = \begin{pmatrix} 2 \\ 5 \\ -3 \end{pmatrix}$$
5. **Write the vector equation of the new line:**
$$\vec{r} = \begin{pmatrix} 2 \\ 5 \\ -3 \end{pmatrix} + t \begin{pmatrix} -2 \\ 5 \\ 2 \end{pmatrix}$$
**Final answer:**
$$\boxed{\begin{pmatrix} x \\ y \\ z \end{pmatrix} = \begin{pmatrix} 2 \\ 5 \\ -3 \end{pmatrix} + t \begin{pmatrix} -2 \\ 5 \\ 2 \end{pmatrix}}$$
