-$\frac{4}{5}$≥y
Multiply both sides by -$\frac{4}{5}$; switch the inequality sign: 1$\leq$-$\frac{5}{4}$y -$\frac{4}{5}$ $\geq$ y Check that -$\frac{4}{5}$ is a solution at the limit: 1=-$\frac{5}{4}$(-$\frac{4}{5}$) 1=1.This is correct. Check that a number less than -$\frac{4}{5}$ is a solution: 1$\leq$-$\frac{5}{4}$ $\times$ -1 1$\leq$-$\frac{5}{4}$.This is correct. When graphing, use a closed circle because -$\frac{4}{5}$ is part of the solutions.
