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]
line passing through the point (16,12) that is perpendicualr to y=1/2x+18
 m = -2 (negative reciprocal od 1/2
 y = -2x + b
12 = -2·16 + b
 44 = b
 y = -2x + 44 is the EQ of that Line
