Step-by-step explanation:
The question is incomplete. I will assume the function is:

Required
Determine the rate of decay
In an exponential function
,
The decay rate of the function is calculated as:

By comparison:

So, the equation becomes:

Make r the subject


<em>The rate of decay is 0.14</em>
Answer:
The rate of change or slope m = -50
Step-by-step explanation:
The slope-intercept form of the line equation

where
- m is the rate of change or slope
Given that there is $500 in Holly's bank account.
Thus, the y-intercept b = 500
It is stated that she takes out $50 from her account each month but doesn't put money back in.
It means the rate of change or slope is decreasing.
Thus, the rate of change or slope m = -50
<u>EXTRA BONUS!</u>
We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form

y = -50x + 500
Here:
The slope m = -50
The y-intercept = 500
