Answer:
Which of the following graphs show a proportional relationship?
Choose all answers that apply:
The answer is A.
Using the proportional relationship concept, the graph of a straight line through the origin is seen in option (A).
So, option (A) is the correct option.
"If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate."
In a proportional relationship, two quantities vary directly with each other.
We can represent relationships in several ways:
1. An equation in the form of y = kx , where k is the constant of proportionality or unit rate.
2. A graph of a straight line that passes through the origin.
3. A set or table of ordered pairs that show equivalent ratios.
4. A verbal description that describes a describe proportional relationship between two quantities.
Explanation for correct option:
According to the given options
The graph of a straight line through the origin is seen in option (A).
So, option (A) is the correct option.
Explanation for other options:
In option(B),
The graph of a straight line does not passes through the origin.
So, option (B) is not correct
In option(C),
Graph is not given
So, it is also not correct
Hence, the graph of a straight line through the origin is seen in option (A).
So, option (A) is the correct option.
