$x$ -intercept: $color(red)(-10)$
$y$ -intercept: $color(blue)(30)$

The $x$ -intercept is the value of $x$ when $y=0$ (i.e. a point on the X-axis)

$3x-y=-30$
with $y=0$
$rarr 3x=-30$
$rarr x=-10$

Similarly the $y$ -intercept is the value of $y$ when $x=0$

$3x-y=-30$
with $x=0$
$rarr -y=-30$
$rarr y=30$
