Determine if linear equation is so put into satandard form.

3x = 5y

7y = 2x + 5x

3/x + 4/y = 2

  • Algebra - ,

    The standard form is Ax + By = C, where A > 0
    so
    first one: 3x - 5y = 0

    second one: you do it
    third one: multiply each term by xy
    3y + 4x = xy
    do you think that is linear?
    Try graphing it

    (by changing it to 3y - xy = -4x
    y(3-x) = -4x
    y = -4x/(3-x) or 4x/(x-3) you can easily find a few ordered pairs.)
