A truck travels from a factory to a gas station in 4 minutes. It stops at the gas station for 2 minutes. The truck then returns to the factory in 4 minutes. Which graph best represents the distance, y, in miles, of the truck from the factory after a certain amount of time, x, in minutes? (5 points)

1 : A graph shows Time in minutes along the x -xis and Trucks distance from factory in miles along the y-axis. The scales on the x- and y-axes are from 0 to 10 at increments of 1. There are three straight lines in the graph. The first line joins ordered pair 0, 0 with 4, 2. The second straight line joins 4,2 and 6,2, and the third straight line joins ordered pair 6,2 with the ordered pair 10, 0.

2. A graph shows Time in minutes along the x-axis and Trucks distance from factory in miles along the y-axis. The scales on the x- and y-axes are from 0 to 10 at increments of 1. There are three straight lines in the graph. The first line joins ordered pair 0, 0 with 3, 2. The second straight line joins 3,2 and 6,2, and the third straight line joins ordered pair 6,2 with the ordered pair 10, 0.
