The slope is $4/3$ .

To find the slope of a line from two points, we use the formula $("change in y")/("change in x")$ or $(y_2-y_1)/(x_2-x_1)$ .

So let's plug in those two points we have (pay attention to the negative signs!):
$(8-0)/(9-3)$

And now let's simplify:
$8/(6)$

$4/3$

The slope is $4/3$ .

Hope this helps!
