What is the equation of the line with slope  m=-7/9  that passes through  (9,-4) ?

$x$+$63 y$ = $- 243$

Explanation:

(Use the equation maker)
$y - - 4$ = $- \frac{7}{9}$ ($x - 9$)
Take things to the other side one by one
$63 y + 252 = - x + 9$
$x + 63 y = - 243$

(I drew this line on GeoGebra and it all worked :)
