Answer to Problem 73E
The graph is straight line and the graph shows with increasing in depth the water pressure also Increases.
Explanation of Solution
Given:
Concept used:
The graph can be calculated through Desmos graphing calculator.
Calculation:
The graph the linear equation
Here y-axis is pressure and x-axis height or depth.
The graph is straight line and the graph shows with increasing in depth the water pressure also increases.
at
At 0 height ofdepth the pressure is 15
(c)
To find:the slope and intercept of y using representation of graph.
(c)
