$(0, - 8)$ $color(blue)(( 0,-8)$

$(4, 0)$ $color(blue)(( 4,0)$

$2 x - y = 8$ $2x-y=8$

The y axis intercept occurs where $x = 0$ $x=0$ :

$2 (0) - y = 8$ $2(0)-y=8$

$- y = 8$ $-y=8$

$y = - 8$ $y=-8$

Coordinates:

$(0, - 8)$ $color(blue)((0,-8)$

The x axis intercept occurs where $y = 0$ $y=0$

$2 x - (0) = 8$ $2x-(0)=8$

$2 x = 8$ $2x=8$

$x = \frac{8}{2} = 4$ $x=8/2=4$

Coordinates:

$(4, 0)$ $color(blue)((4,0)$
