Question 1136220
.
<pre>
Line y + 4 = 0  is the horizontal line line  y = -4, parallel to x-axis.



Any line parallel to it, has an equation y = c,  where "c" is a constant term.



Since the requested line should go through the point (9,-9) with  y-coordinate -9,

this requested line has an equation y = -9.    <U>ANSWER</U>



This equation is in its slope-intercept form, very unique and specific for this special line.
