The given equation is:
$$ \color{blue}{ y = - 9 x + 6 } $$To draw the graph we will find y-intercept and x-intecept.
To find y - intercept we substitute $ \color{blue}{x = 0} $:
$$ \begin{aligned} y &= - 9 x + 6 \\y &= - 9 \cdot \color{blue}{0} + 6\\y &= 6 \\\end{aligned} $$To find x - intercept we substitute $ \color{blue}{y = 0}$:
$$ \begin{aligned} y &= - 9 x + 6 \\\color{blue}{0} &= - 9 x + 6\\x &= \frac{ 2 }{ 3 }\end{aligned} $$So, the graph of the equation is:
