My Kid is Struggling Determining the Flight Path

 Homework:

A plane departs from an airport at the coordinates (2,3) and heads towards another airport at the coordinates (10,8). Your task is to determine the equation of the flight path.

1. Find the slope of the line representing the flight path using the given coordinates.
2. Write the equation of the line in the slope-intercept form (y = mx + b).
3. Explain the significance of each component in the equation in relation to the plane's flight path.

Ensure that your solution includes all the necessary calculations and a brief explanation of each step.

Found the answer on this website https://apostaaviator.com.br/, but I'm not sure if it's correct.
