A ferry is travelling at a constant speed back to the dock, as shown in the graph. Which function represents the relationship between the distance from the ferry to the dock in miles,
y, and the time that the ferry has been travelling toward the dock in hours, X?

it is probably the graph on the bottom right.

step-by-step explanation:

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
