  • Graph: y = -2x + 4
    Verify Student's Answer. Must have m and b.
  • .
    m = 1/1 b = 0
  • .
    y = (6/5)x - 3
  • .
    y = x + 1
  • Graph: y = x - 3
    Verify Student's Answer. Must have m and b.
  • .
    No, since 4 is not equal to -4, the coordinate (4,4) does not satisfy the equation and is not on its graph.
  • Graph: y = 2x - 3
    Verify Student's Answer. Must have m and b.
  • .
    No, since 9 is not equal to -9, the coordinate (-4,9) does not satisfy the equation and is not on its graph.
  • .
    m = 3/1 b = 4
  • .
    m = 3/2 b = -5
  • .
    No, since -5 is not equal to 5, the coordinate (7,-5) does not satisfy the equation and is not on its graph.
  • .
    m = 1/2 b = 0
  • .
    m = 1/1 b = -2
  • .
    y = -x + 4
  • Graph: y = -x -2
    Verify Student's Answer. Must have m and b.
  • .
    y = 2x
  • .
    Yes, since -1 is equal to -1, the coordinate (-4,-1) does satisfy the equation and is on its graph.
  • .
    y = (-8/5)x + 4
  • .
    m = -1/2 b = 4
  • .
    y = (1/3)x + 2
