$y$ -intercept is $-4$

And for every $x$ -value there would be an increase of $3$ in the $y$ value

Choose $x$ values and work out the $y$ values.

$x rarr y$
$0, -4$
$1, -1$
$2, 2$
$3, 5$
$4, 8$
$5, 11$
$6, 14$
$7, 17$
$8, 20$
$9, 23$
$10, 26$

Now plot the points and join them with a straight line.

Whenever there's an increase in the $x$ by $1$ ,. there will be an increase in $y$ by $3.$
graph{y=3x-4 [-10, 10, -5.21, 5.21]}
