Question

20 POINTS!!! PLS HELP <3
Please write it in your own words.

Answer 1

a) point (8.28)
the time is 8 minutes
28 is the water level which is 28 cm

b) 3.5
the function for the situation is y=3.5x

the slope of the function is equal to the value of the unit rate

Answer 2

Answer:

See below ↓↓↓

Step-by-step explanation:

(a)

• The point (8, 28) represents the fact that in 8 minutes time, the water level of the horse trough is at 28 cm

(b)

• The unit rate will be equal to the slope of the graph
• y = 3.5x is given as the equation
• m = 3.5
• Therefore, rate is 3.5 cm/min

(c)

• On taking the slope of these two points it is equal to the slope of the line
• Therefore, we can say that the rise in water level directly varies with time
