Do you have the original function. We're gonna need that. And, show your work. It'll help us out, too.

thats all ive got...btw its 5 times delta x not 5xdelta x ....

oh and my teacher always assign bonus questions for the class after... and usually its about stuff we havent learned yet...could this be solved by limits or derivatives (since we havent learned them yet but we will this month)

Well, here's the thing...we don't show that $\Delta{y}=-5\Delta{x}$ because it just is. This is a trivial case.

I can try something, though...

In an amazing feat, I VonNemo19 will attempt to show that $\Delta{y}=-5\Delta{x}$

Spoiler:
$\Delta{y}=-5\Delta{x}$ TA DA! I did it.

oh wait maybe i should prove by commutativity or associativity instead of solving for x or y

7. or distributivity

Prove what? To prove something, we need some GIVEN information and that the result follows strictly from the given information. all you have is the result.

EG: Given $y=x^2$, show that $y'=2x$

See? Check your notes or something. Look for this mystery info that I speak of.

9. prove that delta y = delta x times 5

Do you know what $\Delta{x}$ and $\Delta{y}$ represent?

lol dude it wouldve been way easier that way but unfortunately my teacher didnt leave any more information...

i contacted a couple of friends and they wrote the same question as me...i didnt write the question wrongfully

Slope - Wikipedia, the free encyclopedia

Read that. Oh, and don't forget to keep digging for that missing information.

Yes my friend, we are doing secant lines and slopes and all that stuff.Im in calculus and I hate slopes and secant lines because i dont get anything. But this question seems more like an algebra question, dont you think?
