Math 1 Exam Review-Graded A
Slope Formula - correct answer-m = y2 - y1 over x2 - x1
Slope Intercept Form - correct answer-y= mx + b
Linear Equations Standard Form - correct answer-Ax + by = c
Quadratic Standard Form - correct answer-y = ax^2 + bx + c
Axis of symmetry formula - correct answer-x = -b over 2a
Quadratic formula - correct answer-x = -b +or- square root of b^2 - 4ac over 2a
Distance formula - correct answer-d = square root of (x2 - x1)^2 + (y2 - y1)^2
Midpoint formula - correct answer-(x1 + x2 over 2, y1 + y2 over 2)
Pythagorean Theorem - correct answer-a^2 + b^2 = c^2
Exponential growth/decay - correct answer-y = a * b^x
Function - correct answer-A line that has no repeating x values (vertical line test)
Parallel Lines - correct answer-Lines with the same slope but different y-intercepts.
Perpendicular Lines - correct answer-Lines with slopes that are the negative reciprocals
of each other (2x, -1/2x)
Systems of Equations - correct answer-Can be solved using three different methods
(graphing, substitution, or elimination)
Systems of Inequalities - correct answer-Graphed using a dotted line for < or >, or a
solid line for < or equal to or > or equal to. Shading done below the line for < and above
the line for >.
FOIL - correct answer-Method of distributing binomials (First, Outer, Inner, Last)
Factoring - correct answer-Can be done using the box method, the GCF and
parentheses, or grouping. A GCF should always be pulled out before this is done.
