Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
we have the points (2,14) and (4,28)
Find out the constant of proportionality k
For (2,14) ----> 
For (4,28) ----> 
so
the value of
therefore
The equation is
The answer to this one will be C
Hope this helps :)
In order to solve this i'd have to know what x equals?? does it tell you?
Answer:
B
Step-by-step explanation:
We have been given a table that shows a linear relationship between x and y. We are asked to find the rate of change change of y with respect to x.
To solve our given problem, we will find the slope of the line passing through the given points.

Let us find slope of line using points
and
.




Therefore, the rate of change of y with respect to x is
.
