3x = 5y

7y = 2x + 5x

3/x + 4/y = 2

**Reiny**, Thursday, December 3, 2009 at 9:01amThe 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.)
