1. Domain/Range

   • Domain= Input (X-Values) Range= Output (Y-Values)

2. Functions

   • Each input has it's own output

3. Lines

   • y-Y1=m(x-X1)
     • Point Slope Form
       • Y=kx
         • Directly Proportional

4. Vertical lines

   • Slope=Undefined
   • Horizontal lines
     • Slope=0
     • Parallel lines
       • Perpendicular
         • Slope: 1/4
       • Slope: -4/1

5. Point of intersection

   • Setting both line equations equal to each other, plugging X back in for Y
