Hello : 
<span>1.5x - 3y = 6
3y = 1.5x - 6
y = (1.5x - 6)/3</span>
        
             
        
        
        
48-126=-78
-78/126= -0.<span>619047619
-0.</span>619047619x100=<span>61.9047619%
This can be rounded to 62%
Hope this helps :)</span>
        
             
        
        
        
Ok so if -6 is the y intercept you look for -6 on the y axis and use rise over run up one over one until you can't plot anymore and then down one over one and do the same thing did that help you Phil?
