when i see a < or > i use a solid or dashed line
When you see the symbol "<" or ">", it typically represents a comparison between two quantities.
If the comparison is "less than" or "greater than," you would use a solid line. For example:
- If x < 5, it means that x is less than 5. In a number line representation, you would use a solid line to indicate that values less than 5 are included in the solution set.
- If y > -3, it means that y is greater than -3. Again, you would use a solid line to represent values greater than -3 in a number line.
If the comparison is "less than or equal to" or "greater than or equal to," you would use a dashed line. For example:
- If a ≤ 2, it means that a is less than or equal to 2. In a number line, you would use a dashed line to indicate that the value 2 is included in the solution set.
- If b ≥ 7, it means that b is greater than or equal to 7. Again, you would use a dashed line to include the value 7 in the solution set.
