Graph line $$ y = - \frac{ 5 }{ 2 } x $$
Solution
The given equation is:
$$ \color{blue}{ y = - \frac{ 5 }{ 2 } x } $$If $ \color{blue}{x = 0} $, then:
$$ y = - \frac{ 5 }{ 2 } \cdot \color{blue}{0} = 0 $$so the the line passes through origin $(0, 0)$.
If x = "something else" (sey $ \color{blue}{x = 2} $), then:
$$ y = - \frac{ 5 }{ 2 } x = - \frac{ 5 }{ 2 } \cdot \color{blue}{ 2 } = -5$$so the the line passes through point $(2, -5)$.
The graph of the equation is:
