Cathlene's Linear Relation Blog Post

Unit 5 Linear Equations

Ordered Pairs on Cartesian Plane or also known as the Coordinate Grid
Ordered Pairs have orders and it is always x and y

A Cartesian Plane or Coordinate Grid

Example #1
In this example the tables are the independent and the chairs are the dependent.

You can also use the horizontal table, but it's good to know both ways.

Example #2

Example #3

Homework

Anabelle's Blog Post: Equivelant Expressions

Combining Integers
Positive + positive= always positive | ex. 3 + 5= 8
Negative + Negative= always negative | ex. -4 -6= -10
Negative + Positive= will always keep the sign of the greatest absolute value | ex. -5 + 7= 12
Positive + Negative= same as negative + positive | 5 - 7= -2
________

Multiplying Integers
Positive x Positive= Positive | ex. (5)(2)=10
Negative x Negative= Positive | ex. (-2)(-3)= 6
Negative x Positive= Negative | ex. (3)(-5)= 15
Positive x Negative= Negative | ex. (-2)(4)= 8

________
Combining Like Terms

Step 1: Collect terms in order of alphabet and degree (in that order) from left to right.

Step 2: Combine and Simplify

When we combine the terms we show our work on the side like this:

________

Removing Brackets while collecting like terms
Step 1: Look at the signs in front of each bracket. If positive simply remove the bracket and keep the terms the same. (Drop the + sign.)

Step 2: Collect like terms.

Step 3: Simplify.

Here is another example:

_______

Step 1: If it is negative multiply out each term by negative and rewrite. (Like switching signs.)

Step 2: Combine like terms.

Step 3: Simplify.

Here is another example:

________

Kim's Blog Post

Degree of a term- the sum of the exponents of any terms, variables.

Examples:

Degree of a polynomial- the greatest sum of any term in a polynomial is its degree.

Examples:

Make a trinomial with 2 variables, degree of 4 and a constant of -6.

Terms- like terms share a common variable and a common exponent.

They should sound alike.

Coloured = positive

White = negative

Homework: 5.1
- CYU #1, 3, 4
-Practice #5-12
- Apply #15, 17, 19, 21-26
- Extend #28, 29, 31
- 5.1 Extra Practice
- 5.1 Homework Book

Anabelle, I choose you to do the next math blog.
