The least to greatest slope, the segments are B, C, and A.
We have given that,
The water level of a tank every minute since it began filling is indicated by segments A, B, and C on the graph below.
A graph represents the water level to fill the tank on Y-axis per time on X-axis.
The rate of increase of water level is indicated by the slope of the segment. The slope is the ratio of rise to run, and is related to the angle the segment makes with the +x axis.
Segments that have more rise for the same run have greater slope. Segments that make a larger reference angle with the +x axis have a larger slope.
Here, segment B has the least slope, followed by C, then A, which has the largest slope.
In order, the least to greatest slope, the segments are B, C, and A.
