What's on the worksheet

  1. Give the slope of every parallel line and every perpendicular line for each line:
    y = 6x - 1y = -\dfrac{3}{4}x + 2y = -x + 82x + 7y = 14y = \dfrac{x}{5} - 3
  2. Compare three lines given by two points, a table and another description.
  3. Compare how far apart two lines are at x equal to 0 and as you step right.
  4. Use slopes to show a triangle has a right angle and name the corner.
  5. Word problem: the slope of a wheelchair ramp, and lines parallel to it.
  6. Test Andre's rule about equations in standard form that give parallel lines.
