Show that the origin and p(7,4) are equidistant from the line L:y = -4x/3 + 20/3

I have seen this question several times, and it has been answered before.
But with Jiskha having removed the search feature, I can't find it.

If I recall, I found the midpoint between (0,0) and (7,4), and subbed
that point into the given line.
If that point satisfied the given equation of the line, then that was it.
