Emily filled an empty horse trough with water. The water level, in centimeters, is proportional to time elapsed, in minutes, since she began filling the trough. The graph shows this relationship. *

(a) Identify the constant of proportionality: _______________


(b) Identify the unit rate: ______________ PER ____________


(c) Explain what (8, 28) means in terms of the graph. Use a complete sentence!

(d) What would the water level be after 20 minutes (hint: use a proportion!)?

Respuesta :

Answer:

(a) The rate that the point 8,28 represents is 3.5 cm/s since 28/8 = 3.5

(b) The unit rate is 3.5 cm/s since the rate is constant.

(c) The two points lie on the same line and that both points results to a rate of 3.5 cm/s.
