If x=2t, y=2t, then dydx= - Infinity Learn

$x = 2 t$

$\frac{d x}{d t} = 2$

$y = \frac{2}{t}$

$\frac{d y}{d t} = \frac{- 2}{t^{2}}$

$\Rightarrow \frac{d y}{d x} = \frac{(\frac{d y}{d t})}{(\frac{d x}{d t})} = \frac{(\frac{- 2}{t^{2}})}{2} = \frac{- 1}{t^{2}}$

If $x = 2 t, y = \frac{2}{t}, t h e n \frac{d y}{d x} =$
