Its non linear because of the x squared. This would indicate an ever increasing answer, not one that has a constant rate. This equation would be quadratic.

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: $y-y_1=m(x-x_1)\\(x_1,y_1)=(5,32), m=3\\$Substituting these values, we obtain:\\y-32=3(x-5)\\This is the equation of the function in point slope form.$
