Mathematics

• quadrant 2 - (- , +)
• quadrant 1 - (+ , +)
• quadrant 3 - (- , -)
• quadrant 4 - (+ , -)
• if-then statement - composed of two clauses (if clause and then clause)
• P - hypothesis
• Q - conclusion
• if-then, converse, inverse, contrapositive
• if-then - if p then q
• converse - if q then p
• inverse - if not p then not q
• contrapositive - if not q then not p
• inequality - is a mathematical statement where one expression is not equal to another
• linear inequality - uses greater than, less than, greater than or equal, less than or equal, and not equal
• equation - indicates the value of both mathematical expressions are equal
• linear equation standard form - Ax + By = C
• linear inequality - standard form - Ax + By > C
• if - then is also known as conditional statement
• graphing linear inequalities in two variables - set of all points in the rectangular coordinate system who has ordered pairs that satisfy the inequality
• separates the plane into two region - half - planes
• the line that separates the plane - plane diider
• graph the RESULTING equation with a SOLID LINE if the ORIGINAL inequality contains greater than or equal or less than or equal
• if the inequality contains < or > symbol, use a broken line
• < - shade below the line
• > - shade above the line
• less than or equal - below the line
• greater than or equal - above the line
• slope (m) - rise/run
• slope (m) - positive left-bottom, right top
• slope (m) - negative right-botttom, left top
