The Mega Monstrosity roller coaster has many hills and turns. It slowly rides up the 315-foot hill, then it rolls along the peak. Then, it drops 195 feet and continues to travel along winding tracks. The roller coaster then travels up a 60-foot hill, and then drops 90 feet. It whips through a turn, then zips up a 30-foot hill. Finally, it drops 120 feet, coasts up a 30-foot hill, and then stops. Sasha and Juan team up to sketch a graph that possibly models the elevation the roller coaster travels.

A graph showing elevation in feet on the y-axis & time in seconds on the x-axis. There are 11 line segments. Segment f is between (0, 0) & (105, 315). Segment g is between (105, 315) & (135, 315). Segment h is between (135, 315) & (150, 120). Segment i is between (150, 120) & (180, 120). Segment j is between (180, 120) & (225, 180). Segment k is between (225, 180) & (240, 90). Segment l is between (240, 90) & (270, 90). Segment m is between (270, 90) & (300, 120). Segment n is between (300, 120) & (315, 0). Segment p is between (315, 0) & (330, 30). Segment q is between (330, 30) & (360, 30). The y-axis has marks every 30 feet, & 1 mark between every 30-foot mark. The x-axis has marks every 60 seconds, & 3 marks between every 60-second mark.

Which statements correctly describe the quality and accuracy of their sketch?

Select all that apply.

The segments g, i, and ℓ, are accurate, but segment q should end at point (360,0).The segments g textsf comma i textsf comma and ℓ, are accurate, but segment q should end at point

The segments g, i, ℓ, and q accurately represent no change in elevation.
The segments g textsf comma i textsf comma ℓ, and q accurately represent no change in elevation.

They selected 15 feet for the scale of the y-axis for elevation and 15 seconds for the scale of the x-axis for time, which is reasonable.
They selected 15 feet for the scale of the y textsf negativeaxis for elevation and 15 seconds for the scale of the x textsf negativeaxis for time, which is reasonable.

The segments f, j, m, and p accurately represent the increase of the elevation of the hills.
The segments f textsf comma j textsf comma m textsf comma and p accurately represent the increase of the elevation of the hills.

They selected 30 feet for the scale of the y-axis for elevation and 60 seconds for the scale of the x-axis for time, which is reasonable.
