The linear graph y = 2x + 3 represents the relationship between the data provided.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have input and output in the table:
From the points:
(3, 9) and (6, 15)
[tex]\rm \left(y-9\right)=\dfrac{\left(15-9\right)}{6-3}\left(x-3\right)[/tex]
(y - 9) = 2(x - 3)
y = 2x + 3
Thus, the linear graph y = 2x + 3 represents the relationship between the data provided.
