Hi
the standard slope-intercept form for an equation of a line is:
 {{{y = highlight_green(m)x + highlight(b)}}}  where m is the slope and b the y-intercept.  
(2, 3) and 
(5, 2)   m = 1/-3 = -1/3

***Using point-slope form, {{{y - y[1] = highlight_green(m)(x - x[1])}}}
 y -2 = (-1/3)(x-5)
   y = (-1/3)x  + 5/3 + 2
   y = (-1/3)x + 11/3

Wish You the Best in your Studies.
