Question

Solve graphically the following systems of linear equations. Also find the coordinates of the points where the lines meet axis of $y$.
$x+2y-7=0$,
$2x-y-4=0$

Answer 1

The lines$:$

$x+2y-7=0$

$2x-y-4=0$

plotting graph $:$ $x+2y-7=0$

$x$	$0$	$7$	$-1$
$y$	$\frac{7}{2}$	$0$	$4$

plotting graph $:$ $2x-y-4=0$

$x$	$0$	$2$	$3$
$y$	$-4$	$0$	$2$

The solution $(3,2)$

The point where they meet $y$-axis $,$ $(0,\frac{7}{2})$ and $(0,-4)$ $.$
