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

Express the following linear equations in the form $ax + by + c = 0$ and indicate the values of $a$, $b$ and $c$ in each case : $2 x+3 y=9.3 \overline{5}$

Write each of the following equations in the form $ax + by + c = 0$ and indicate the values of $a$, $b$ and $c$ in each case :

$(i)$ $2 x+3 y=4.37$

$(ii)$ $x-4=\sqrt{3} y$

$(iii)$ $4=5 x-3 y$

$(iv)$ $2 x=y$

For each of the graphs given in Fig. select the equation whose graph it is from the choices given below :

$(a)$ For Fig. $(i)$,

$(i)$ $x+y=0$           $(ii)$ $y=2 x$            $(iii)$ $y=x$             $(iv)$ $y=2 x+1$

$(b)$ For Fig. $(ii)$,

$(i)$ $x+y=0$           $(ii)$ $y=2 x$            $(iii)$ $y=2x+4$             $(iv)$ $y=x-4$
