Equation of a Straight Line and Writing Equations for Horizontal and Vertical Lines

The video tutorial explains how to write equations for vertical and horizontal lines, emphasizing their intersections with the x-axis and y-axis. It introduces the y=mx+c formula for straight lines, detailing the roles of the gradient (m) and y-intercept (c). The tutorial covers calculating the gradient by examining changes in y and x, and demonstrates deriving line equations from given coordinates.

What does the value of 'm' represent in the equation y = mx + c?

Describe the process of finding the equation of a line from two coordinates.
