Determine the equations of the lines from the graph, representing objects' distances from Benin over time.

Step 1: Determine the equations of the lines from the graph.
The x-axis represents time in hours, and the y-axis represents distance in km from Benin.

Line 1 (Object starting from Agbor):
This line starts at $(0, 80)$ (80 km from Benin, which is Agbor).
It appears to pass through the point $(2, 30)$ (2 hours, 30 km from Benin).
The slope ($m_1$) represents the speed of the object from Agbor.
