What We've Learning
Solving Systems of Linear Equations/Inequalities
This whole school year, we've been working on solving equations. All that process is is to do the inverse operation (the opposite operation) on BOTH sides of the equal sign (=) until the variable is solved (isolate the variable).
There are three methods to solve Systems: 1 is graphing; 2 is substitution; and 3 is elimination.

Linear Functions
In class, we looked at different representations of functions (graphs, mapping diagrams, and input-output tables. The most fundamental information for students to remember is with functions each x can have exactly and only one y value. This means x-values cannot repeat (y-values can). We also learned about the vertical line test.

Pythagorean Theorem
The Pythagorean Theorem is a mathematical concept/theorem that states the sum of the sides squared will be equal to the hypotenuse's length squared in right triangles. (a-squared plus b-squared equals c-squared). We will be defining and applying the Pythagorean Theorem in order to determine a right triangle's missing side's length. We will also be solving word problems based on the Pythagorean Theorem.
