The slope of a function is the average rate of change of the function.
The meaning of the slope is that: <em>Kayla's charges per child is #2</em>
The function is given as:
![\mathbf{f(x) = 2x + 4}](https://tex.z-dn.net/?f=%5Cmathbf%7Bf%28x%29%20%3D%202x%20%2B%204%7D)
A linear function is represented as:
![\mathbf{f(x) = mx + c}](https://tex.z-dn.net/?f=%5Cmathbf%7Bf%28x%29%20%3D%20mx%20%2B%20c%7D)
Where:
m represents the slope of the function.
By comparison,
![\mathbf{m = 2}](https://tex.z-dn.net/?f=%5Cmathbf%7Bm%20%3D%202%7D)
From the question, we understand that:
The function models the average money charged to babysit children
So, the interpretation of the slope is that:
Kayla's charges per child is #2

Answer:
The answer is B, your welcome
Y=55
Explanation:
If you’re looking to see how 11 and y would match -9 and -45 you would find the unit rate of -9 and -45.
-9/-9=1
-45/-9=5
So if the y is going up by 5’s it would be 55.
You can make use of the slope-intercept form of a line which is:
y = mx + b
Substitute m and the coordinates of a point in the line to find b,
-2 = (2/5) (5) + b
b = -4
The equation is
y = (2/5) x - 4
In standard form:
(2/5)x - y = 4
2x - 5y = 4
