Finding the rate of change is like finding the slope.  Subtract the y values to find the change in the number of dollars.  Subtract the x values to find the change in the number of video games.  Divide the first number by the second number.

And it looks like the initial value was 350 dollars since we have the ordered pair (0,350)

So, i need to subtract all of the y values and then all of the x values? i got a negative number - is that correct?

anonymous · Answer

i subtracted the y values and got -3,350
