Express the following linear equations in the form $ax + by + c = 0$ and indicate the values of $a$, $b$ and $c$ in each case : $x-\frac{y}{5}-10=0$

Find two solutions for each of the following equations :

$(i)$ $4 x+3 y=12$

$(ii)$ $2 x+5 y=0$

$(iii)$ $3 y+4=0$

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. $(ii)$,

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

$(c)$ For Fig. $(iii)$,

$(i)$ $x+y=0$           $(ii)$ $y=2 x$            $(iii)$ $y=2x+1$             $(iv)$ $y=2 x-4$

Write four solutions for equations : $\pi x+y=9$

Draw the graph and linear equations in two variables : $x – y = 2$
