In this video, we'll learn how to find the equation of a line in intercept form. We leverage the previously derived form - 2-point point form for this. If we are given two intercepts, we first find the coordinates of points on x and y axes. We then use these points to get the equation in 2-point point form. If we generalise the result, we get the intercept form equation. We also solve a practice problem where we have to find the equation of a perpendicular.
