Hi
Using the point-slope formula, {{{m =(y[2] - y[1])/(x[2] - x[1])}}}
(0,5) AND 
(1,3)   m = 2/-1 = -2
*[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]
y = -2x + b  |using ordered pair Pt(0,5) to solve for b
5 = b
 y = -2x+5
