The right answer is the constant of proportionality
If two variables are related and this relationship is that there is a<em> constant ratio</em> between them, then we are talking about proportionality. There are two types of proportionality.
1) Direct Proportionality:
In a mathematical language this is given by this equation:
where 
is in fact this constant of proportionality. If 
<em>increases,</em> 
also <em>increases</em> at the same rate. On the other hand, If <em> decreases, </em> also <em>decreases</em> at the same rate.
2) Inverse Proportionality:
In a mathematical language this is given by this equation:
where is also called the constant of proportionality. If <em>increases,</em> <em>decreases</em> at the same rate. On the other hand, If <em>decreases,</em> <em>increases</em> at the same rate.

EXPLANATION
The area of the square coaster is represented by:
We split the middle term to obtain,
We factor by grouping to get,
Since area of a square is l² , it means the side length of the square is
b) The perimeter of a square is given by
We substitute the length in terms of d, to obtain;
Or
Answer:
y = − 1
Hope this helps!
Step-by-step explanation:
Alright so this is our equation:
y − 3 = 2 ( x − 1 )
We will substitute:
x = − 1
So now our equation looks like this:
y − 3 = 2 ( −1 − 1 )
Now we will get rid of the parentheses:
y − 3 = − 2 − 2
Solve the left side:
y − 3 = − 4
Now add 3 on both sides to find out what y is:
y − 3 = − 4
+3 +3
Add:
y = − 1
Yay! We found our answer! Nice job everyone!
Parentheses (brackets/braces) are done first according to the order of operations.
