$\frac{401}{8}$

Step-by-step explanation:

$\sf{y\:can\:also\:be\:refered\:to\:as\:f(x)}$

$\sf{Zeros\: are\: also\: called\: roots.}$

The roots (zeros) are the values where the graph intersects the -axis. To find the roots (zeros), replace with 0 and solve for .

$y = - 8x + 401\\\\0 = - 8x + 401\\$

$-8x+401=0\\\\-8x+401-401=0-401\\\\-8x=-401\\\\\frac{-8x}{-8}=\frac{-401}{-8}\\\\x=\frac{401}{8}$

$\sf{Therefore,\: the\: zero\: of\: this\: function\: is\: \frac{401}{8}$
