Answer:
0.0138 minutes/meter
Step-by-step explanation:
A linear regression model is given by the following general equation:

Where 'y' changes as a function of 'x', 'c' is a constant and 'm' is the slope that dictates the rate of change.
The given equation for the duration of a dive (DD), in minutes as a function of depth (D) in meters is:

Comparing this equation to the general model, the rate of 0.0138 minutes per meter, is our slope 'm'
Therefore, the slope of the regression line is 0.0138.
Between 2 and 3, after the 2 1/4 point, but before the halfway point.

Answer:
A
The leading coefficient is negative.
Step-by-step explanation:
Quadratic equation:
A quadratic equation has the following format:

The leading coefficient is a.
a negative:
The graph of the function is concave down, that is, it displays values that approach negative infinity.
a positive:
The graph of the function is concave up, that is, it displays values that approach up infinity.
In this question:
Displays values that approach negative infinity, so the leading coefficient is negative, and the correct answer is given by option A.
