How can you determine if two lines are perpendicular?

  • Algebra -

    you can find the slope of the two lines...when it is perpendicular
    m1*m2=-1
    m1=one of the slope
    m2=the second slope
    if you multiply the slopes together, you will get -1 if it is perpendicular.

    Multiply the slope of one by the slope of the other. If the product is -1, they are perpendicular.
