For a proportional relationship, the constant is found dividing all values of y by each respective value of x.
<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.
The constant can be represented as follows:

Hence the constant is found dividing all values of y by each respective value of x.

Answer:
135 degrees
Step-by-step explanation:
Octagons have 8 sides which make up 8 angles that are all equal to each other.
The angles must sum up to 1080 degrees in an octagon.
Take 1080 degrees and divide by 8 angles and you will get 135 degrees.
