1, Might not be precise 
2, Can be hard to plot the graphs
3, If there are many solutions that will be really hard to plot sometimes. 
This is just from the top of my head. 
        
                    
             
        
        
        
Answer:
C. The slope of the function is -2 and the y-intercept is 4.
Explanation:
The y-intercept is the point when x = 0. On the table when x is 0, y is 4.
The slope of the function is -2 because the y value is going down by 2 for each +1 of x.
       x │ y
     -2 │ 8
      0 │ 4
   ↓ +1   ↓ -2 
       1 │ 2
   ↓ +1   ↓ -2 
      2 │ 0

Answer:
- <u><em>A. 6,000 miligrams</em></u>
Explanation:
A <em>balance scale</em> is balanced when the weights on both sides are equal. Then, since the image shows that both sides are equal, the weight of the <em>6-gram weight</em>, placed by Henry on one side of the balance scale is equal to the weight of the <em>ballet slipper </em>placed on the other side.
- Weight of the balance slipper = weight of the 6-gram weight
- Weight of the balance slipper = 6 grams
<u>Conversion of units: </u> 
- 6 grams × 1,000miligrams/1gram = 6,000 miligrams
- Weight of the balance slipper = 6,000 miligrams
That is the option A.
