Hi,         
the standard slope-intercept form for an equation of a line y = mx + b  
where m is the slope and b the y-intercept.  
 In this case b = 8 and 
the slope is -3/2 = -1 using {{{m =(y[2] - y[1])/(x[2] - x[1])}}}  (5-8)/(3-0)
Slope can also be determined by graphing. 
Note:line slants to left, slope is negative 
And as y changes by one, so does x
 y = -x + 8
