Answer:
The correct option is 3.
Step-by-step explanation:
Form the given figure it is noticed that the line is passing through the points (60,4) and (120,8).
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
Where, k is the constant of proportionality or slope.
The slope of a line is defined as
[tex]k=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]k=\frac{8-4}{120-60}[/tex]
[tex]k=\frac{4}{60}[/tex]
[tex]k=\frac{1}{15}[/tex]
Therefore option 3 is correct.
