Lesson 6-1 Example Solve. VACATION Arleta and Zina were on vacation. Zina went hiking and climbed a hill that was 236 feet above sea level. Arleta went scuba diving and dove 110 feet below sea level. Which girl was at the lower elevation? Understand Read the problem. Write what you know. Arleta was at 110 feet below sea level. Zina was at 236 feet above sea level.

Lesson 6-1 Example Plan Pick a strategy. One strategy to use is to draw a diagram. Draw a number line that is vertical instead of horizontal.

Lesson 6-1 Example Solve Sea level is at 0. Graph the zero. The lower elevation is 110 feet below sea level. Below sea level is negative. Graph Arleta’s elevation. Above sea level is positive. Graph Zina’s elevation. Arleta was at the lower elevation.

Lesson 6-1 Example Check Look over your solution. Did you answer the question?
