A graph can show direct, inverse and joint proportions.
y is not directly proportional to x because the graph does not pass through the origin
From the graph, we can see that:
When x = 0, y > 0
i.e. y is greater than 0, when x equals 0
This means that, the equation of the graph is:
[tex]\mathbf{y = mx + b}[/tex], where b > 0
A proportional equation is represented as:
[tex]\mathbf{y = mx}[/tex]
Hence, y is not directly proportional to x because the graph does not start from the origin
