An argument came up on the name of an equation and i wanted your esteemed letsrun input, wit, sarcasm, contempt and all.
2X + 3Y = 5 is a linear equation.
Whats the best description for something like 3X = 5X + 7.
What would you call it? Is it still a linear equation because it becomes X = -7? Or is there some other word to better describe it?
Secondly if you asked someone to graph 3X = 5X + 7 would you expect a point on the number line or a vertical line?

Nope, it's not a linear equation. You would plot this on a graph as a vertical line that passes through the point (0,-7) extending indefinitely in both directions.
You didn't specify what space you're in. If you're in R, then no it is not a linear equation. If you're in R^2 (Cartesian plane), then yes it is.
Sure, but the first equation can also be extended indefinitely in both directions.

First figure out how you got x = -7 from 3x = 5x + 7
G Bra? what a big tit you must be.

Ignoring the algebraic solution mistake, this can be written as:
2X + 0Y = -7 in standard form, therefor, yes, it is a linear equation. As Kartelite said, how it graphs depends on your framework, but yes, typically as a line.
Now I know what all the geeks from my h.s. are doing...

It's not a linear equation, but it's graph is a line? WTF? Do you even know why they're called linear?
