Rate of change is another way to say slope.
Slope is (the change in y) / (the change in x).
The formula for slope is:
m = (y2 - y1)/(x2 - x1), with (x1, y1) being one point and (x2, y2) being the second. What you need to do is order the slopes from smallest to largest because slope means the same thing as rate of change.
#17. First, you need to find the slope of function A. To do this, I’m choosing two different points I see on the graph: (1,1) and (2,1). I now plug these into the slope formula:
m = (1-1)/(2-1) = 0/1 = 0.
The slope for function A = 0
To find the slope for function B, you can choose any two points. I’m going to use (3,0) and (6,1)
m = (1-0)/(6-3) = 1/3
The slope for function B is 1/3
For function C, you are already given the slope. That equation is in something called slope-intercept form (y=mx+b), where the x is being multiplied by the slope.
The slope on function C = 1/4
So,, A has the smallest slope, C has the second smallest slope, and B has the largest slope.
#18. The two points in using to find the slope for function A are (0,-3) and (1,0).
m = (0+3)/(1-0) = 3/1 =3
The slope for function A is 3
The two points I’m using for function B are (-2, 10) and (0, 20)
m = (20-10)/(0+2) = 10/2 = 5
The slope for function B is 5
The slope for function C is 1. When the slope is 1, it is not written because any number (other than 0) times 1 equals 1.
Function C has the smallest slope, function B has the second smallest slope, and function C had the largest slope.
It would probably be better for you to try 19 and 20 on your own, and let me or anyone else on Brainly know if you have any questions or something doesn’t make sense.
I hope this has helped!
Answer:
y=-7
Step-by-step explanation:
y-y1=m(x-x1)
y-(-7)=0(x-5)
y+7=0
y=0-7=-7
Complete Question
The histogram from this question is shown on the first uploaded image
Answer:
The first quartile is 
The median is 
The third quartile is 
The mean is 
Step-by-step explanation:
From the question we are told that
The total number of girls is n = 74
Generally the median is mathematically represented as
![Median = \frac{\frac{n}{2} +[ \frac{n}{2} + 1] }{2}](https://tex.z-dn.net/?f=Median%20%20%3D%20%20%5Cfrac%7B%5Cfrac%7Bn%7D%7B2%7D%20%20%2B%5B%20%5Cfrac%7Bn%7D%7B2%7D%20%2B%201%5D%20%20%7D%7B2%7D)
So
![Median = \frac{\frac{74}{2} +[ \frac{74}{2} + 1] }{2}](https://tex.z-dn.net/?f=Median%20%20%3D%20%20%5Cfrac%7B%5Cfrac%7B74%7D%7B2%7D%20%20%2B%5B%20%5Cfrac%7B74%7D%7B2%7D%20%2B%201%5D%20%20%7D%7B2%7D)

From the histogram 
fall under 2 fruits per day
Generally the first quartile is mathematically represented as
![1st \ Q = \frac{\frac{n}{4} + [\frac{n}{4} + 1] }{2}](https://tex.z-dn.net/?f=1st%20%5C%20Q%20%3D%20%20%5Cfrac%7B%5Cfrac%7Bn%7D%7B4%7D%20%2B%20%5B%5Cfrac%7Bn%7D%7B4%7D%20%2B%201%5D%20%20%7D%7B2%7D)
=> ![1st \ Q = \frac{\frac{74}{4} + [\frac{74}{4} + 1] }{2}](https://tex.z-dn.net/?f=1st%20%5C%20Q%20%3D%20%20%5Cfrac%7B%5Cfrac%7B74%7D%7B4%7D%20%2B%20%5B%5Cfrac%7B74%7D%7B4%7D%20%2B%201%5D%20%20%7D%7B2%7D)

From the histogram 
girl fall under 1 fruit per day
Generally the third quartile is mathematically represented as
=> 
=> 
From the histogram 
fall under 4 fruits per day
Generally from the histogram table the frequency [number of subjects (girls) ] and the servings of fruit per day can be represented as
Total
x(servings per day ) 0 1 2 3 4 5 6 7 8
f (number of subjects ) 15 11 15 11 8 5 3 3 3 
xf 0 11 30 33 32 25 18 21 24 
Generally the mean is mathematically represented as
![\= x = \frac{1}{ \sum f} * [\sum xf]](https://tex.z-dn.net/?f=%5C%3D%20x%20%3D%20%5Cfrac%7B1%7D%7B%20%5Csum%20f%7D%20%20%2A%20%5B%5Csum%20xf%5D)

Answer:
16x 144
Step-by-step explanation:
4x times 4x then 12 times 12 than that is you answer beacons you can ad 12 and 4x because the 12 has no x
