@haleyelizabeth2017   don't say straight line, because a vertical line is not a function.

solomonzelman · Answer

We know that you exclude a vertical line though, so it's okay, just don't forget to actually mention that.

haleyelizabeth2017 · Answer

that is true.....sorry :( I haven't done this for 2 years so I don't quite remember how to explain it.....haha

solomonzelman · Answer

So you are in trig now ?

haleyelizabeth2017 · Answer

no. last year in geo we didn't really do much with this stuff.....I did it in alg 1 but I am in alg 2 this year haha next year I will be in trig :)

solomonzelman · Answer

I skipped alg 1 :)

haleyelizabeth2017 · Answer

oh haha

solomonzelman · Answer

I didn't like geometry when I took it though. easy course, and waste of time.

solomonzelman · Answer

Have fun y'all :) .... it can be function if it is not continuous to, but still be linear, like a line that discontinues at some value (more likely in a real life situation).

but no needs to worry about that.
