To represent the set of heights needed to ride the roller coaster, we need a graph that shows all heights starting from 54 inches and above. This means the graph should indicate 54 inches as the starting point and include all values greater than that.
Among the options you've provided:
- The first number line, starting at 58 and ending at 53, does not represent heights of 54 inches or above.
- The second number line, starting at 58 and ending at 54, also does not accurately reflect heights of 54 inches or above.
- The third number line appears to label heights starting at 58 and includes 54, however, it seems to imply inclusion or opening at 54.
- The last number line, starting at 58 and ending at 55, again, does not show heights of 54 inches or above.
None of the given options directly show a graph starting from 54 inches and accurately indicating all heights greater than or equal to 54 inches. The correct representation would ideally include a solid line starting at 54 inches and extending onward.
If you were to evaluate any options based on proximity or assumption, you'd look closely at the third number line. However, none of the provided options seems perfectly correct based on the requirement of ≥54 inches. If you can define exact inclusivity and ranges per the options, that might lead to a more definitive answer.
