Answer:
y = -  x -
 x - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
19x + 15y = - 6 ( subtract 19x from both sides )
15y = - 19x - 6 ( divide all terms by 15 )
y = -  x -
 x -  , that is
, that is 
y = -  x -
 x -  ← in slope- intercept form
 ← in slope- intercept form
