A graph of this linear function (y = 3x + 6) is shown in the image attached below.
What is a graph?
A graph can be defined as a type of chart that is commonly used for the graphical representation of data on both the horizontal line (x-axis) and vertical line (y-axis) of a cartesian coordinate.
Next, we would simplify the given linear function by dividing all through by 5 as follows:
5y - 15x = 30
5y/5 - 15x/5 = 30/5
y - 3x = 6
Rearranging the linear function, we have:
y = 3x + 6
In this context, we can reasonably and logically deduce that only the graph of a proportional relationship such as a linear function is always characterized by a straight line with all of the data points passing through the origin (0, 0).
In conclusion, a graph which represents the given linear function does not show a proportional relationship between the value of x and y.
