the graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes:
part a: describe how you can use similar triangles to explain why the slope of the graph between points a and b is the same as the slope of the graph between points a and c. (4 points)
part b: what are the initial value and slope of the graph, and what do they represent? (6 points)
