      In a grade 9 (ages 14-15) introductory algebra lesson, the class is exploring how the m and b in the equation y = mx + b are related to the graph of a linear function. During a class discussion about these relationships, a student asks if it is possible for the graph to have "two dots on the y-axis"- that is, whether is it possible for the linear function to have more than one y-intercept.
