Math II First Partial

1. Cartisian Plane

   • Distance: we can measure the distance in the cartisian plane
   • Midpoint: we can know the midpoint in the cartisian plane
   • Range and Domain: we can know the range and domain in a cartisian plane
     • Interval
     • Inequality
     • Numerical Line
   • Is it a function?
     • Is x repeating? No, function. Yes, move along...
       • Is the y same for the x? Yes, function. No, just a relation

2. System of Equation

   • There are three Methods to find the system of equations
     • Elimination
     • Substitution
     • Graphing
   • Types of System
     • Dependent
       • Identity: the system will always touch, so it will always be true
     • Independent
       • Condition: the Independent system has only one touching point,
     • Inconsistent
       • Contradiction: the Inconsistent system is a contradition since it will never be true, the line will never touch
   • Linear System

3. Linear Fuction

   • Slope intercept: y=mx+b
     • horizontal line: horizontal line is related with the slope y intercept because the if x equal 0, the line will be horinzontal
     • vertical line: vertical line is related with the slope y intercept because the if y equal 0, the line will be vertical
     • 2 other formulas
       • General Formula: Ax+By+C=0
       • Standard: Ax+By=C
   • Parallel lines
     • Perpendicular line
   • Equations
     • Absolute Value: to get the abs. value we must solve equations sometimes
     • Properties: what type of equations
