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?

Step-by-step explanation:

Let the triangles be ADC and BEC.

Point D has coordinates of (0, 154), point E has coordinates of (0, 110).

ΔADC

The slope of AC

ΔBEC

The slope of BC

As we can see the slopes are equal

The y-intercept or initial value is represented by the point C and has coordinates of (0, 66)

The line is:

The initial value is the depth of 66 m where the shark is.

The slope is the 44 m increase of the depth every minute.
