I am completely unsure on how to go about taking points from a line and putting them into standard form.

If I have points (3, 0) and (0, -4) how would I put that into a standard form? I know that the standard form will have x and y on the same side, but it seems the steps on doing so are what confuse me.

If anyone could please explain the process of putting the points listed above into standard form I would highly appreciate it.

Thank you for your help!
