Answer:

y = 2x

Step-by-step explanation:

Use Rise over Run. The rise(up/down) is 2 and the run(sideways) is 1. The slope is going up, not down so the 2 is positive. So, it is positive 2/1, which you can write as 2.

I'll use subscript notation for brevity, i.e.

\dfrac{\partial f}{\partial x}=f_x

3.

f(x,y,z)=xy+z^2\implies\begin{cases}f_x=y\\f_y=x\\f_z=2z\end{cases}

x(r,s)=s^2\implies\begin{cases}x_r=0\\x_s=2s\end{cases}

y(r,s)=2rs\implies\begin{cases}y_r=2s\\y_s=2r\end{cases}

z(r,s)=r^2\implies\begin{cases}z_r=2r\\z_s=0\end{cases}

By the chain rule,

f_r=f_xx_r+f_yy_r+f_zz_r=2xs+4zr=2s^3+4r^3

f_s=f_xx_s+f_yy_s+f_zz_s=2ys+2xr=6rs^2

4.

x(r,s,t)=r+s-2t\implies\begin{cases}x_r=1\\x_s=1\\x_t=-2\end{cases}

y(r,s,t)=3rt\implies\begin{cases}y_r=3t\\y_s=0\\y_t=3r\end{cases}

z(r,s,t)=s^2\implies\begin{cases}z_r=0\\z_s=2s\\z_t=0\end{cases}

By the chain rule,

f_r=f_xx_r+f_yy_r+f_zz_r=y+3xt=3rt+3r+3s-6t^2

f_s=f_xx_s+f_yy_s+f_zz_s=y+4zs=3rt+4s^3

f_t=f_xx_t+f_yy_t+f_zz_t=-2y+3xr=3r+3s-12rt
