Given:
The area model.
To find:
The area as a sum and area as a product.
Solution:
The four terms of the area model are .
The area as a sum is the sum of all the terms of given area model.
Area as a sum =
=
The area as a product is the factor form of sum of all the terms of given area model.
Area as a product =
=
=
Therefore, the area as a sum is and the area as a product is
.
(x₁,y₁) = (2,-3)
(x₂,y₂) = (2,9)
To determine the slope using two points lie on the line, we could use the following formula
m =
plug in the numbers
m =
m =
m =
m = undefined
The slope is undefined, the line is vertical
