Question

Determine if the ordered pair marked by the circle is a solution for the inequality

Answer 1

When the inequality sign is < / > (less than/greater than), the line is a dotted line.

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

If "y >" (y is greater than.....), the shaded area is above the line.

If "y < " (y is less than....), the shaded area is below the line.

[points in the shaded area are solutions for the inequality. If the point is on the line and the line is ≤ / ≥, it is a solution]

- The point outside of the blue shaded area is not a solution because it has to be in the shaded area.

- The point on the line is not a solution because the line is a dotted line, which means that the point can't be equal to the points on the line.

- The point inside the blue shaded area is a solution.
