the graph shows the depth,y, in meters, if 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?

part b: what are the initial value and slope of the graph, and what do they represent?

Answer 1

Answer: Look at the step-by-step

Step-by-step explanation:

Part A: We can use two right triangles that represent rise over run to explain the slope of points A and B which has the same slope of points A and C. Since there will be two right triangles, they are considered similar triangles.

AB: 154 - 110= 44

44/2= 22

AC: 154 - 66 = 88

88/2=44

This means that the slope of the two sets of points is 44, and it represents the rate of change of the shark travelling away from the ocean’s surface every minute.

Part B: The initial value is 66 (m), and it represents the initial position of the shark at 0 minutes.
