Answer:
1st option y-5 = 3(x-1)
Step-by-step explanation:
graph shows y intercept of 2
1st option has a y intercept of 2
Area of ceiling: 6 x 5 = 30 square meters:
Area of 4 walls = 107 - 30 = 77 square meters
2 walls = 6 + 6 = 12 meters long
2 walls = 5 + 5 = 10 meters long
12 + 10 = 22
77 square meters / 22 meters = 3.5 meters
The walls are 3.5 meters high.
