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]
f(x) = -9x - 2    |slope m = -9  and  y-intercept is -2   
Line crossing the y axis at Pt(0,-2)
m = -9/1: as y increases/decreases by 9, 
             x increases/decreases by 1 in the opposite direction
