3.2.3 Point-Slope Form (continued) Example 2 Using Point-Slope Form to Graph An equation of the form y − y 1 = m ( x − x 1 ), called the point-slope form of a linear equation, describes a line with slope m that contains the point ( x 1 , y 1 ). A linear equation that is given in point-slope form can be graphed by identifying the slope and a point on the line from the equation, then using the slope to find a second point on the line, as demonstrated by Prof. Burger in Example 2.
