Writing Suppose the relationship between x and y is proportional. When x is 29, y is 275.5. Find the
constant of proportionality of y to x. Use the constant of proportionality to find x when y is 408.5. Use
pencil and paper. Explain how you can tell a relationship that is proportional from a relationship that is
not proportional.
The constant of proportionality is I.
(Type a whole number or a decimal.)

Answer:
a) I=9,5
b) x=43
c) I is same for every value of y and x if the relationship is proportional.
Step-by-step explanation:
The constant of proportionality I can be found as:
a)
We are given: x= 29, y=275.5 we need to find constant of proportionality I
Using formula:
So, constant of proportionality I = 9.5
b)
Now, we need to find x when y is 408.5.
Using the above formula we can find x
c)
A relationship is proportional if for every value of x and y we have a relation: where I is constant. The value of I is same for every value of y and x.
If a relationship is not proportional then for every value of x and y we have don’t have a relation: where I is constant. The value of I is different for every value of y and x.
