For a zero order reaction, the integrated rate law is given by:

$[\text{A}{]}_t=-kt+[\text{A}{]}_0$

Comparing this equation with the equation of a straight line $y=mx+c$, we get $y=[\text{A}{]}_t$ and $x=t$.

The slope of the graph $m$ is $-k$ and the y-intercept $c$ is $[\text{A}{]}_0$.

Therefore, the slope of the graph of $[\text{A}{]}_t$ against time is $-k$.

Answer: $-k$
