Find the integral of $-5$ using the table of common integrals rule $\int a\mathrm{d}z=az$.
$$-5z$$
If $F\left(z\right)$ is an antiderivative of $f\left(z\right)$, then the set of all antiderivatives of $f\left(z\right)$ is given by $F\left(z\right)+C$. Therefore, add the constant of integration $C\in \mathrm{R}$ to the result.
