Lesson Notes The goal of this lesson is for students to know that the graph of an equation in the form of = or = , where is a constant, is the graph of a vertical or horizontal line, respectively. The graph of this set is, by the rule for prescribing first coordinates to points, exactly those points on the vertical line which intersects X at the directed distance a from O. For example, y = 3 is a horizontal line. The graph is a horizontal line passing through the \(y\)-axis at \(–1\) as shown. Register or login to make commenting easier. The concept of slope simply does not work for vertical lines. Follow along with this tutorial as you see how use the information given to write the equation of a horizontal line. For lines that are neither vertical nor horizontal, they are perpendicular if and only if the slope of one is the negative reciprocal of the slope of the other.
