Equation Of Parallel Lines

In this video, Lucy explains how to find the equation of parallel lines. She begins by reviewing the y = mx + c format and the concept of gradient. Lucy illustrates that parallel lines have the same gradient and demonstrates how to find the equation of a parallel line passing through a given point. She provides a step-by-step example, showing how to substitute coordinates to find the y-intercept. The video concludes with a summary and a prompt to explore perpendicular lines in another video.
