$-\frac{4}{5}\geq y$
Multiply both sides by $-\frac{4}{5}$; switch the inequality sign. $1\leq-\frac{5}{4}y$ $1\times-\frac{4}{5}\geq-\frac{5}{4}y\times-\frac{4}{5}$ $-\frac{4}{5}\geq y$ Check that $-\frac{4}{5}$ is a solution at the limit. $1=-\frac{5}{4}(-\frac{4}{5})$ $1=1\checkmark$ Check that a number less than $-\frac{4}{5}$ is a solution. $1\leq-\frac{5}{4}\times-1$ $1\leq\frac{5}{4}\checkmark$
