How do I do this? Graph the line containing the given pair of the points and find the slope. (2,4), (-6,-4).

  • Algebra -

    slope = m = (-4-4)/(-6-2) = -8/-8 = 1
    y = m x + b
    y = 1 x + b
    4 = 2 + b
    b = 2
    so

    y = x + 2 is our line

    check if it goes through second point
    -4 = -6 + 2 yes, check
