How it is done! Solve the following inequation m + 3 > 5 m > 2 -3 -3 m > 2 The inequation can be graphed on number line. Draw arrow in the direction of the inequality sign. -5 -4 -3 -2 -1 1 2 3 4 5 Use an open circle as the inequation has no equal sign.

How it is done! Solve the following inequation b - 2 > -5 b > -3 +2 +2 b > -3 Graph on number line. -5 -4 -3 -2 -1 1 2 3 4 5 Draw arrow in the direction of the inequality sign. Use an open circle

How it is done! Solve the following inequation 4w ≤ 12 w ≤ 3 ÷4 ÷4 w ≤ 3 Graph on number line. -5 -4 -3 -2 -1 1 2 3 4 5 Draw arrow in the direction of the inequality sign. Use a CLOSED circle Because of equals sign.

How it is done! Solve the following inequation h ÷ 2 ≥ -1 h ≥ -2 x2 x2 h ≥ -2 Graph on number line. -5 -4 -3 -2 -1 1 2 3 4 5 Use an CLOSED circle Because of equals sign. Draw arrow in the direction of the inequality sign.
