Answer:
The correct option is 1.
Step-by-step explanation:
If a line passing through two point, then the equation of line is
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
From the given graph it is clear that the line is passing through the points (0,0) and (5,3). So, the equation of line is
[tex]y-0=\frac{3-0}{5-0}(x-0)[/tex]
[tex]y=\frac{3}{5}(x)[/tex]
The equation [tex]y=\frac{3}{5}(x)[/tex] represents the same proportional relationship as the graph.
Therefore the correct option is 1.
