Options A, C and D are functions.
In a function, for every number for 'x' there is only one 'y'. So, if you have two ordered pairs in a choice that have the same number for 'x', that is not a function.
Remember an ordered pair is written (x, y).
B is not a function as:
(x, y)
(1, -2)
(1, -3)
(1, -4)
^ All of the x-coordinates are the same.
E is not a function as:
(x, y)
(6, -1)
(6, -8)
^ Two of the x-coordinates are the same.
Thus, A, C and D are functions.
The constant of the proportional relationship graphed in this problem is of 10.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the points on the graph are: (0,0), (2,20), (4,40), ..., hence the constant is:
k = 40/4 = 20/2 = 10.

Answer:
The answer is 2
, we need to use the distance between point formula; I recommend you search in the internet another examples.
Step-by-step explanation:
We need to calculate the distance between points, so we need to use the formula d=
You can use Janes house (-5,-2) or friends house like (3,-4) point 1 or 2, it is the same way.
when we substitute in the formula
:
d = 
d=
d=
= 
We need to reduce this result, so we need to find two number wich on of those can we solve the square root, if we divide 68/4 we find:
d=
And 4 has exact square root result, so the result in:
2
