A fluid flow is defined by $u=f_1(x, y)$ and $v=f_2(\mathrm{x}, y)$ (Table 5,1). Determine the equation of the streamline passing through point $M\left(x_M y_M\right)$. Also, find the acceleration components of the particle at point $M\left(x_{M_1} y_M\right)$ and sketch the acceleration on the streamline.
$$
\begin{aligned}
&\begin{array}{|c|c|c|c|}
\hline u=f_1\left(x_i y\right), \frac{m}{s} & y=f_2\left(x_i y\right) / \frac{\mathrm{m}}{\mathrm{s}} & x_m \cdot m & y_m m \\
\hline 7 x^2-y^2 & -x & 1 & 3 \\
\hline
\end{array}\\
\end{aligned}
