Finding The Equation Of A Line Through 2 Points PART 1

In this video, Lucy explains how to find the equation of a straight line passing through two points. She covers calculating the gradient using the formula (y2-y1)/(x2-x1) and determining the y-intercept using the y=mx+c format. The video emphasizes understanding the gradient and y-intercept concepts and provides a step-by-step guide to forming the line equation. Lucy also previews the next part, which involves solving without a graph.
