The y-intercept of a graph is the point where the graph touches the y-axis.
The best describes the y-intercept of the graph is (a) the initial water level of the river is 16 ft
From the attached graph, we observe that the graph crosses the y-axis at y = 16
This value represents the initial value of the graph.
In other words, the initial water level of the river
So, the y-intercept means that:
The initial water level of the river is 16 ft
Hence, the true statement is (a)
