D. The Number of Solutions to a System of Equations
As you saw when graphing systems of equations in Lesson 7.1, different systems can have different numbers of solutions. When a system has either one or two real solutions, the algebraic solution looks similar to those you’ve seen in earlier units. However, if a system has zero or an infinite number of real solutions, the algebraic solution may seem odd. The following investigation explores this.
