What is true of the shaded area of a linear inequality?

SELECT ALL THAT APPLY

• the shaded area represents possible answers (correct combinations)

• the shaded area is either above or below the line, representing either "greater than" or "less than"

• the shaded area is just to add color and make the graph easier to read

• the only part of the answers that are correct are the points exactly on the line

• the shaded area is determined by whether the slope of the line is positive or negative

• n > -1

• n < -1

• n > 3
