Answer:
140
Step-by-step explanation:
   70%            200
  ----------    *    ----------  =  70*2 = 140
   100%              1
you cross out the 2 zeros from the 100% so it will be one then croos out the 2 zeros from 200 and you will have 70 * 2 and you will get 140
 
        
                    
             
        
        
        
to get the equation of a line, we simply need two points, say for the Red one ... notice in the graph the lines passes through (0,2) and (-1,6), so let's use those

now, for the Blue one, say let's use hmmm it passes through (0,2) and (1.6)
