Instructions

  1. Print this webpage. If you can, set your printer to Grayscale for faster printing.
  2. Fold each page down the middle along the solid vertical line.
  3. Cut along the dotted horizontal lines.
  4. Optional: Use tape, glue, or staples to hold the two sides of each flashcard together.

This will print 5 pages (5 terms/page). This box will be automatically hidden when printing. Return to Set Page

Point Slope Equationy-y1=m(x-x1)
Point Slope Standard FormAx+Bx=C
Vertex(-b/m,c)
RelationSet of pairs of input and output values
DomainSet of inputs (x- value)
RangeSet of outputs (y-value)
Mapping DiagramLinks domain to range
FunctionRelation in which one element of domain is paired with EXACTLY one element in range
Vertical Line TestIf passes 2 points on graph=> NOT a function
Coinciding LinesSame Line ( All Real )
Inconsistent LinesParallelI
Independent LinesHave one solution; Different slopes
SubsitutionSolving for one variable in one equation & plugging it into the second
Elimination- Linear CombinationAdd equations together to eliminate a variable
Quadratic Functionf(x)=ax2+bx+c
Linear Functionf(x)=x+c
Vertex of a Quadratic Function(-b/2a, Plug it in)
Vertex Form of a Quadratic Functiony=a(x-h)2+k
