*To solve an inequality, it's the same as solving an equation; isolate the variable to one side.
For this, all you need to do is divide both sides by -4. And since we are dividing by a negative, flip the inequality sign and your inequality is [tex]x\leq\frac{1}{4}[/tex]
Now to graph this. Since x can be "equal to" 1/4 ( ≤ = less than or equal to), you will have a closed circle on 1/4. And since x can also be "less than" 1/4, the arrow will be going to the left of 1/4.
