a) As the constants are equal, the situation represents a proportional relationship.
b) The constant of 2/3 cupcakes per minute means that in a minute, 2/3 of a cupcake is made.
<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 constants for each situation are:
k = 30/45 = (30/15)/(45/15) = 2/3 = 20/30.
Since the constants are equal, the situation represents a proportional relationship.
The constant of 2/3 cupcakes per minute means that in a minute, 2/3 of a cupcake is made.

Answer:
A) The point( -1 , 5) is satisfies the given graph
B) The point( 3 , 1/125) is satisfies the given graph
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given graph
y =
Put the point ( -1 , 5)
Put y =5 and x =-1
The point( -1 , 5) is satisfies the given graph
ii)
Given graph
y =
The point( 3 , 1/125) is satisfies the given graph
