A fish tank at a salmon hatchery holds 10,000 litres. The tank needs to be drained to be cleaned each season. After 20 minutes of draining, the water is at the ¾ full line.

a) Define the two variables in this situation.
Independent variable:
Dependent variable:
b) Assuming this relationship is linear, write an equation in slope-intercept form to represent this situation.
Equation:
c) Explain what the slope of the line would represent in this situation.
d)Identify what the horizontal (x) intercept of the graph would represent in this situation.
e) Explain whether it would be appropriate for the graph of this equation to have a line or just points.
f) If the tank started draining at 9:20a.m., calculate when it will have 3,500 L remaining to drain.
