The given equation is:
$$ \color{blue}{ y = \frac{ 1 }{ 10 } x } $$If $ \color{blue}{x = 0} $, then:
$$ y = \frac{ 1 }{ 10 } \cdot \color{blue}{0} = 0 $$so the the line passes through origin $(0, 0)$.
If x = "something else" (sey $ \color{blue}{x = 10} $), then:
$$ y = \frac{ 1 }{ 10 } x = \frac{ 1 }{ 10 } \cdot \color{blue}{ 10 } = 1$$so the the line passes through point $(10, 1)$.
The graph of the equation is:
