Check the solutions of the equation $x -2y = 4$ and which are not : $(0,\,2)$
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. $(iii)$,
$(i)$ $x+y=0$ $(ii)$ $y=2 x$ $(iii)$ $y=2x+1$ $(iv)$ $y=2 x-4$
Draw the graph and linear equations in two variables : $x + y = 4$
Draw the graph and linear equations in two variables : $x - y = 2$
Express the following linear equations in the form $ax + by + c = 0$ and indicate the values of $a$, $b$ and $c$ in each case : $x=3 y$
