Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
This is the symmetric property of equality, and in a more general form it can be written as: if a=b then b=a.
This is not to be confused with communicative property, which says that the order doesn't matter in some operations, such as addition, and can be written as a+b=b+a
To make that a perfect square polynomial,
follow these steps:
1. Take the co-efficient of x term: here -16
2. Divide it by 2: -16/2 = -8
3. Square it. : (-8)^2 = 64
Thats it! 64 is the missing term you need :)
