Plot the following equations graphically and the intersection point:
$2 x + y = 6$
$2 x - y + 2 = 0$

Open in App

Solution

$2 x + y = 6,$

$2 x - y + 2 = 0,$

So We take a point from graph, $(1, 4)$

Equation form $x = 1, y = 4.$

So,
$2 x + y = 6$

$2 (1) + 4 = 6$

$2 + 4 = 6.$

And

$2 x - y + 2 = 0$

$2 (1) - 4 + 2 = 0$

$2 - 4 + 2 = 0.$
