PLEASE HELP MEE Starting at 7:00 a. m., Lin spent a day hiking through a canyon. This graph shows her elevation (in meters) at some different times. Negative values of x represent times earlier than noon, and positive values of x represent times later than noon.
a. What was Lin’s elevation at noon? Explain how you know.
b. At 10:00 a. m., Lin’s elevation was 7 meters. Add this point to the graph.
c. At 1:00 p. m., Lin was at sea level. Add this point to the graph.
d. Did Lin’s elevation increase or decrease between 7:00 a. m. and 2:00 p. m.? Explain how you know.
e. Lin climbed downward from 2:00 p. m. to 3:00 p. m. Add a point to the graph that shows her possible elevation at 3:00 p. m. Write the elevation and explain your reasoning.
