A graph that shows the solution set for y ≤ 9 is shown on the number line in the picture below.
In Mathematics, an inequality is a relation that compares two or more numbers and variables in an algebraic equation based on any of the following inequality symbols:
- Less than or equal to (≤).
- Greater than (>).
- Greater than or equal to (≥).
- Less than (<).
Based on the information provided, we can logically deduce that solution set is given by;
y ≤ 9.
Therefore, the solution set means a solid dot would be placed at point 9 on a number line with an arrow that decreases to the left as correctly depicted by the graph shown below.
