Question

Express the linear equation $y-2=0$ in the form $ax+by+c=0$ and indicate the values of $a,b$ and $c$.

Answer 1

Compare the equations

The given equation is,

$y-2=0$

This can be rewritten as,

$0.x+1.y-2=0$

Compare this with the standard linear equation,

$ax+by+c=0$

We have $a=0,b=1,c=-2$

Hence, the values of $a,b$ and $c$ are $0,1$ and $-2$.
