$- 16$

Roots are the points where the graph intercepts with the x-axis $(y = 0)$ .

$y = 0$ at the roots

The root at $x = - 16$ was found by solving for $x$ when $x - (- 16) = y$ and $y = 0$ .

The factor is $x + 16$

Combine all the factors into a single equation.

$y = x + 16$

Remove parentheses.

$y = x + 16$
