Answer:
The slope and y-intercept are
and
, respectively.
Explanation:
The first-order polynomial has the following form:
![y = m\cdot t + b](https://img.qammunity.org/2020/formulas/mathematics/middle-school/q508k63g0xqwkko25kbag6yiccbgttutv1.png)
Where:
- Slope, in meters per minute. (Ascension rate)
- Time, in minutes.
- y-Intercept, in meters. (Initial depth)
- The depth of the submarine with respect to the sea level, in meters.
Slope and y-intercept are determined herein:
![m = (3\,(mi)/(min) )\cdot ((1609\,m)/(1\,mi) )](https://img.qammunity.org/2020/formulas/mathematics/middle-school/bub8sfdeifyy2epgdo0988miprpj9cf97x.png)
![m = 4827(m)/(min)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mswdq524hao70rup7kvppzrmjm333bxpuy.png)
