easy

Express the following linear equations in the form $ax + by + c = 0$ and indicate the values of $a$, $b$ and $c$ in each case : $2 x=-\,5 y$

Option A

Option B

Option C

Option D

Solution

We have $2 x=-5 y $ $\Rightarrow 2 x+5 y=0$

$ \Rightarrow $ $(2) x+(5) y+0=0$

Comparing with $a x+b y+c=0,$ we get $a=2,\, b=5$ and $c=0$.
