I think you messed up on the values Remember this is simple interest not compound interest, therefore the rate of change stays the same Check your table

OpenStudy (gokuporter):

So I just add 2% Interest based on the first deposit?

OpenStudy (anonymous):

Yup, You take 2% of 500 And ONLY add that, you do NOT need to take 2% of any other number :)

OpenStudy (gokuporter):

The next one after 510.00 would be 520.00?

OpenStudy (anonymous):

Yup

OpenStudy (gokuporter):

It would be +10 every time?

OpenStudy (anonymous):

So you would just add 10 everytime

OpenStudy (anonymous):

Yep ^ said it before I did lol Good job

OpenStudy (anonymous):

So what would be your rate of change? And if the rate of change isn't changing what type of function is it?

OpenStudy (gokuporter):

Is it a Linear Function?

OpenStudy (gokuporter):

@Brill ?

OpenStudy (anonymous):

Oh my bad didnt get the notification Yes it is So what would be the equation for this?

OpenStudy (gokuporter):

y= mx + b

OpenStudy (anonymous):

Yeah, but what values would you substitute for m and b?

OpenStudy (gokuporter):

500 substitute b. I don't know what substitutes m.

OpenStudy (gokuporter):

Does 10 Substitute m?

OpenStudy (anonymous):

Well what's the rate of change?

OpenStudy (anonymous):

Yup lol^ Said it before I could get the question out

OpenStudy (anonymous):

Good job :)
