Determine if linear equation is so put into satandard form.
3x = 5y
7y = 2x + 5x
3/x + 4/y = 2

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(3x) = 4x
y = 4x/(3x) or 4x/(x3) you can easily find a few ordered pairs.)
