Answer:
Step-by-step explanation:
y = (-1/2)x + 4 is the equation of a straight line with y-intercept (0, 4) and slope -1/2.
To graph this, first plot the y-intercept (0, 4). 
Recall that slope m = rise / run, and notice that the slope in this particular case is -1/2 = rise / run, or rise = -1 and run = 2.
Starting with your pencil point on (0, 4), move the point 2 units to the right (run = 2), arriving at (2, 4).  Next, move your pencil point 1 unit down, to (2, 3).
Draw a straight line through (0, 4) and (2, 3).

Answer: Each cylinder weighs 1/40 of a ton.
Step-by-step explanation:
If we were dealing with a total of 1 ton, than we can easily see that each cylinder would be one twentieth. Because we are dealing with a total of 1/2 ton, we can now figure out that each cylinder is 1/40 tons.
 
        
             
        
        
        
First we need to subtract 8.50 from 22.2 we get 13.7. Then once we divide 13.7 by 3.84 we get 3.57. Which should be the answer.
