This graph shows the rate of a scuba diver’s ascent to the surface. What does the y-intercept of the graph represent? Graph of a diagonal line on a coordinate plane going up and to the right with Time (min) on x-axis and Depth (m) on y-axis. When min is 0, m is -30. When min is 3, m is -10

B. The scuba diver started her ascent at the surface of the water.
C. The scuba diver ended her ascent 35 meters below the surface of the water.
