Sometimes we're only given a couple of points on a line and then asked to write a linear equation. When given this information, it's easiest to use point slope form. Point slope form can be written using one point and the slope or when given two points since we can calculate the slope from the two points. Once we have an equation in point slope form it can be rewritten in slope-intercept or standard form.
