Finding Equations of Straight Lines from Coordinates

The video tutorial explains how to find the equation of a straight line using both graphing and analytical methods. It covers the general equation y = mx + c, where m is the gradient and c is the y-intercept. The tutorial provides examples of calculating the line equation through given points, both graphically and analytically, and includes a complex example involving multiple points and finding a missing coordinate.
