Question

For what value of $c$ , the linear equation $2 x + c y = 8$ has equal values of $x$ and $y$

Open in App

Solution

Verified by Toppr

Let $x = y = α$
$\Rightarrow 2 α + c α = 8$
$\Rightarrow c = \frac{8 - 2 α}{α} = \frac{8}{α} - 2$
Graph of $y = \frac{8}{x} - 2$ would be $y = \frac{8}{x}$ shifted by 2 units downward.
