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
the answer would be C because 7(-1) -5(-7) would be -7+35 which equals 28
8.25*40= $330 a week
330*12= $3960 a year
Answer:

Step-by-step explanation:
area of a rectangle formula
a = length x width
given the area and the width we need to find the length
120=length x 15
to do so we divide the area by the width
120/15=8
so we can conclude that the length of the rectangle is 8
