INTEGRATED MATH 1- you may use a calculator, NOT a phone

• Direct vs. Inverse Variation- solving for k
• Distributing 3xy ( 2x + 5 )
• FOILing ( 2x + 7 ) ( 3x - 1)
• Factoring out a GCF: 10x + 25
• Factoring by Grouping: 3a + 6 + 4a + 8
• Factoring a trinomial: x2 + 5x + 6
• Expanding and Simplifying: 4 ( a + 3 ) + ( 2a + 5 ) ( 3a + 1 )

INTEGRATED MATH 2

• Bias and 5 types of Sampling Methods: (cluster, convenience, random, stratified, systematic)
• Cross multiplication
• Isolating a variable involving fractions
• Solving for slope given two points ( -3, 2 ) and ( 7, 5 )
• Solving for the y intercept given a slope and point: m = -2 and ( 4, -3 )
• Graphing in Standard Equation: y = mx + b
• Domain and Range: All Real vs. Segment vs. Ray
• Parallel and Perpendicular Slopes
