Math Concepts

1. Equations

   • System of equations. It includes 2 or more equations that are needed to find 2 or more variables.
     • Substitution
     • Addition/Elimination
     • Graphing
     • Types of system. Is the result of the given answers when you solve a system of equations.
       • Independent
       • Dependent
       • Inconsistent
       • Perpendicular and parallel lines. Obtained by seeing the type of system you got.
   • Absolute value. Equations that have a part of absolute value can be equal o 2 numbers.

2. Cartisian plane

   • Domain and Range. We can define it by looking at the points in the cartesian plane.
     • Is it a function? By seeing how many times x repeats.
     • Vertical and horizontal lines. Those that show the value either of domain or range.
     • The interval, inequality, and numerical line are different ways in which you can represent the domain and range.
   • Linear Function. A simple linear function with only one independent variable does a straight line when is plotted on a cartesian plane.
     • Y-intercept, slope, value of x
     • Graphs
       • Math statements.
         • Open & Closed questions
           • Always (Yes)
           • Never (No)
           • Sometimes
       • The MidPoint between 2 different points that are represented.
       • Distance between the different points
       • Graphing
     • Three types of presentation
       • Slope-intercept form
       • General
       • Standard
     • Applications of liner systems. Word problems where you need to include a linear equation or function.
       • Linear properties. Different methods that you can use in order to get the answer of a linear function or equation.
         • Commutative
         • Associative
         • Distributive
         • Identity
         • Inverse
