What does communitive property mean

What you meant was the "commutative" property.

So we can say that when adding:

"Commutative means that the order does not make any difference in the result."

Example:

5 + 6 = 6 + 5

a + b = b + a

The commutative property does not hold for subtraction.

Example:

4 - 1 ≠ 1 - 4

a - b ≠ b - a

Ok, now does the commutative property hold true for multiplication?

2 x 3 = 3 x 2

2 x 3 x 4 = 4 x 3 x 2

Yes.

What about division?

12 ÷ 4 ≠ 4 ÷ 12

The commutative property does not hold for division.

4+2=-2. 1+2=3. y=-2/3x+b. 2=4/3+b. 2/3=b. the answer is y= -2/3x+2/3
