PLEASE SOLVE I WILL MARK BRAINILEST AND YOU GET 50 POINTS!!!!!!!!!!!
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) What rate does the point represent? Explain.

(b) What is the unit rate for the situation in terms of centimeters/minute? Explain.

(c) Explain how the points and show that the water level varies directly with the time elapsed.

The graph is an illustration of a proportional linear equation.

(a) What point (8,28) representFrom the graph:x represents time and y represents the water level

So, point (8,28) means that:

The water level at 8 minutes is 28 cm

(b) The unit rate
the equation is given as: y = 3.5x

The above equation is a proportional linear equation.

Hence, the unit rate is 3.5 cm per seconds

(c) How (8,28) and (6,21) shows direct variation

These points show direct variation because the unit rates at the points are the same.

The unit rate is calculated in the photo :)

Hence, points 8,28 and 6,21 show that the water level varies directly with the time elapsed.
