The document discusses writing equations in point-slope form. It provides the point-slope form equation y - y1 = m(x - x1) and examples of writing equations in point-slope form given a point and slope, finding the slope and a point from an equation, writing an equation in slope-intercept form, and finding the equation of a line given two points in point-slope form. The homework assigned is to complete practice problems writing and identifying equations in point-slope form.
