Hi
*[tex \LARGE\ Using \ the \ standard \ slope-intercept \ form \ for \ an \ equation \ of \ a  \ line \ y = mx + b ] 
*[tex \LARGE\ where \ m \ is \ the \ slope \ and \ b \ the \ y-intercept]
x+ 2y = 9  |solving for y
  y = -(1/2)x + 9/2  Slope m = (-1/2)
Parallel lines have identical slopes:
 y = (-1/2)x + b  |using ordered pair Pt( 6,9) to solve for b
 9 = (-1/2)6 + b
 12 = b
 y = (-1/2)x + 12   OR in standard form: x + 2y = 24</PRE>
