Gia is attending a trekking camp. she walks from her tent to a hilltop in 4 hours. she has a picnic with her friends on the hilltop for 3 hours. gia walks back to her tent in 2 hours. which graph best represents the distance, y, in miles, traveled by gia for a certain amount of time, x, in hours?

a) a graph shows time in hours on the x-axis and gia’s distance from tent in miles on y-axis. the graph shows three straight lines. the first straight line joins ordered pairs 0, 0 and 2, 6. the second straight line joins ordered pairs 2, 6 and 5, 6. the third straight line joins ordered pairs 5, 6 and 9, 0.
