2.1

2.1: Linear functions

pg1 A&A HL - Topic 2 - Functions Notes.j

Problems:

  1. Find the slope of a line passing through (-1,0) & (3,-8):

  2. Parallel, perpendicular, or neither: y=3x+4 & y=3x+7

  3. Parallel, perpendicular, or neither: y+x/3=2 & y=3x-5

  4. Find eq. of a line that's parallel to y=0.5x+5 and passes (4,-5)

  5. Find eq. of a line that's perpendicular to y=2x-3 and passes (-5,3)

Answer
      -2      
Answer
