Question

Find the rate of change
y=-3x+1

pradipgr817 · Answer

take dy/dx, it is -3

parthkohli · Answer

Our rate of change is simply the $\text{slope}$ in this case.

parthkohli · Answer

@jmallis Do you not agree with this? We just have a line!

parthkohli · Answer

Why does one need to take stuff to calculus?

pradipgr817 · Answer

yes slope is constant

@ParthKohli, that's because they don't really understand calculus. ;P

parthkohli · Answer

Yes. In a linear equation, rate of change is simply the slope... right?

pradipgr817 · Answer

when you can use it. you use it

What if a kid is in the sixth grade? Will you really care to explain what $d \over dx$ is? Just ask him what number he sees along with $x$!

pradipgr817 · Answer

thats your choice

parthkohli · Answer

So, very, ridiculous.

pradipgr817 · Answer

@ParthKohli thats you know he's in sixth. you went you sent simple.

Let's all follow @@pradipgr817's school of thought!

@jmallis, to find the slope of the super complicated function$$y=-3x+1,$$you have to take its derivative, as follows:$$\frac{dy}{dx}=\lim_{\Delta x\to0}\frac{-3(x+\Delta x)+1+3x-1}{\Delta x}=\lim_{\Delta x\to0}\frac{-3\Delta x}{\Delta x}=-3.$$Did you get that?

:P
