Answer:
y-32=3(x-5)
Step-by-step explanation:
The swimming pool is being drained at a constant rate of 3 inches per hour, therefore:
- The rate of change, Slope, m=3 inches per hour
If the depth of the water after 5 hours is 32 inches.
The <u>depth is the dependent variable(as its values varies with time)</u> while the <u>time is the independent variable</u>, we can write this as a pair (x,y)=(5, 32).
The point slope form of the equation of a line is of the form: 
Here is my answer. I hope you can read it and see how I solved it. I’m not 100% sure on this one, but I think I’m correct.
