A mixed number is converted to an improper fraction by
.. a +b/c = (ac +b)/c
Of course, dividing by a fraction is the same as multiplying by its inverse.
.. (a/b) / (c/d) = (a/b) * (d/c)
I don't see how the numbers on the chart work with the table because I
got 1(1), 3(2,2,2), 6(4,4,4,4,4,4), 10(6,6,6,6,6,6,6,6,6,6), 5(8,8,8,8,8), 3(10,10,10) ,1(12)
that is how i see the chart, sorry if i got it wrong.
Answer:

Step-by-step explanation:
We begin with 
First, lets turn this mixed number into an improper fraction/

Now that we have this, we can square it and then simplify it.

Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange x - 2y = - 3 into this form
Subtract x from both sides
- 2y = - x - 3 ( divide all terms by - 2 )
y =
x +
← in slope- intercept form
with m = 
• Parallel lines have equal slopes, thus
y =
x + c ← is the partial equation
To find c substitute (- 1, 2) into the partial equation
2 = -
+ c ⇒ c = 2 +
= 
y =
x +
← in slope- intercept form
Multiply through by 2
2y = x + 5 ( subtract 2y from both sides )
0 = x - 2y + 5 ( subtract 5 from both sides )
- 5 = x - 2y, thus
x - 2y = - 5 ← in standard form
