    First you should simplify the inequality and get n by itself:

    3n – 10 ≥ 2      Add 10 on both sides

    3n ≥ 12       Divide 3 on both sides

    n ≥ 4

    When the sign is ≤ or ≥ (less/greater than or equal to), the line is a solid line.

    When the sign is < or >, the line is a dotted line.

    If the variable is > than the function (like y > 3x + 2, or x > 2y²) The shaded area is above the line (or going in the positive direction)

    If the variable is < than the function (like x < 2, or x < 5z – 7), The shaded area is below the line.

    Since we got n ≥ 4,

    If n is an x value, or n = x, you would have a horizontal line at y = 4, but if n is a y value, n = y, you would have a vertical line at x = 4. The shaded area should be above the line, or to the right of the line since n is > 4. (Sorry, I don’t know if n = y or n = x, hope this clarified things)

    Answer:

    n ≥4

    Step-by-step explanation:

    3n -10 ≥ 2

    Add 10 to each side

    3n -10+10 ≥ 2+10

    3n ≥12

    Divide by 3

    3n/3 ≥12/3

    n ≥4
