Either order is correct.
Small example: let's take
. Then
By the commutative property, we can write
By the associative property, we can regroup consecutive terms.
By the associative property again, we can regroup terms and write
Commutativity:
Associativity:
You can show by induction that this holds in general for
so that
.
Answer:
Slope (m) = -1
Step-by-step explanation:
(2,1);(0,3)
(x1,y1)=(2,1)
(x2,y2)=(0,3)
Use the slope formula:
m = y^2 - y^1 / x^2 - x^1
= 3-1/0-2
=2/-2
=1
The picture is blurry but is this the problem if so see steps 4(3)+4(6)= 12+24=36
