Start with the given inequality
Subtract 5 from all sides
Divide every side by -4 to isolate c. Remember, dividing every side of an inequality by a negative number flips the inequality signs
Rearrange the inequality.
So the solution in interval notation is: [2,8)
Now let's graph the solution set
Note: at there is a closed circle (which means this point is included) and at there is a open circle (which means this point is excluded)
