It is quite simple actually since it is simple division with the negative rules.
Just simplify the problem and use the negatives to determine if it is positive or negative. (two negatives equal a positive and one negative equals a negative)
Answer:
3) Prove the lengths are the same.
Step-by-step explanation:
Congruent is a measure of the lengths of the sides not the slopes.
<span>Points (1, 1), and (2, 2) are on a line which has a slope of 1
ok?
The only point that lies on this line is (3,3).

If 1/6 of the pan was left and there were 2 pieces left you just need to set 1/6 equal to 2/some number, this allows you to say that 1/6=2/x --> x/6=2-->x=12.
My explanation might be a little poor since this becomes fairly fundamental later on but hopefully it helps.
