The given equation is:
$$ \color{blue}{ y = 4 x + 4 } $$To draw the graph we will find y-intercept and x-intecept.
To find y - intercept we substitute $ \color{blue}{x = 0} $:
$$ \begin{aligned} y &= 4 x + 4 \\y &= 4 \cdot \color{blue}{0} + 4\\y &= 4 \\\end{aligned} $$To find x - intercept we substitute $ \color{blue}{y = 0}$:
$$ \begin{aligned} y &= 4 x + 4 \\\color{blue}{0} &= 4 x + 4\\x &= -1\end{aligned} $$So, the graph of the equation is:
